-*- mode: text; mode: fold -*-

Changes since B0.99-15
1. lib/edt.sl: Hard-coded escape sequences \e= and \e> were swapped.
   This affected the use of the application keypad on systems that did
   not have terminfo entries specifying these strings.
2. src/file.c: if write failed, report errno and num failed bytes.
3. src/screen.c: Unlock buffer files when exiting as a result of a
   fatal error.
4. lib/cmode.sl: c_indent_line would auto-insert // even when
   configured not to do so by the user.
5. lib/site.sl: Collapse multiple occurances of / characters in
   filenames that appear on the command line.
6. src/ledit.c: If a file to be loaded really a directory, then skip it.
   (SANGOID@lloydadriatico.it)
7. src/*.c: use _SLvsnprintf instead of vprintf to
   avoid buffer overflows.  Also use safe_strcpy instead of strcpy.
8. src/sysdep.c: tweak to expand_filename to deal with very large
   filenames (much larger than OS permits).
9. lib/compress.sl: avoid using a regexp to get extname.
10. src/pty.c: tweaked for compiling with CYGWIN--- Requires slang
    1.4.5 if you intend to build a cygwin version.
11. src/main.c: If jed-script is symlinked to jed, then the result is
    equivalent to running jed with the -script option.  This is useful
    for using jed in an executable script, e.g., 
    
         #!/usr/bin/env jed-script
	 vmessage ("Script name: %s", __argv[0]);
	 quit_jed ();
	 
    Also, if the script defines a function called "jedscript_main",
    then that function will get called after the file is loaded.

12. doc/rtl/keys.tm: get_key_binding documentation corrected by
    Guenter Milde <G.Milde@physik.tu-dresden.de>.
13. lib/filter.sl: filter_region function was not working.
14. src/menu.c: New function: menu_select_menu.  This enables a menu
    item to be executed from a function call, e.g.,
    
       menu_select_menu ("Global.W&indows.&Color Schemes");
       
    will popup the color-schemes menu.
15. src/ledit.c: bug-fix involving loading files such as xxx-1.0.sl
    when loaded as ()=evalfile("xxx-1.0").
16. src/colors.c: new intrinsics: get_color, add_color_object.  The
    idea behind these was conceived by Francesc Rocher.  A
    "custom_color" function analogous to "custom_variable" was also
    added.
17. src/wterm.c: patch from Paul Shirley <paul.shirley@ntlworld.com>
    to have ALT keys return scancodes instead of win32 virtual keycodes.
18. doc/tm/rtl/*.tm: Fixed synopsis lines and various other
    documentation improvments (Guenter Milde <G.Milde@physik.tu-dresden.de>)
19. src/indent.c: New intrinsic: what_syntax_table returns the name of
    the current syntax table.
20. src/unix.c: fixed a problem in the filename expansion routines
    that affects older systems that do not have glob.h.
21. lib/site.sl: If Tab_Always_Insert_Tabs is non-zero, the pressing
    the tab key will cause a tab to be inserted.  The default value is
    0.
22. When objects (files or buffers) are loaded, they are given the
    full path name.  This means that the slang pseudo-variable
    __FILE__ will expand to the full pathname of the file being loaded.
23. lib/cmode.sl: treat formfeeds like whitespace
24. lib/comments.sl: Add support for java comments (Nathan Smith
    <nsmith@cs.ohiou.edu>)
25. lib/os.sl: x_*_selection functions aliased to x_*_cutbuffer if
    undefined.  This permitted #ifdefs to be removed from lib/mouse.sl
    to avoid problems with mouse.sl byte-compiled with jed but used
    with xjed.
26. src/xterm.c: Handle selection events while waiting for keyboard
    input.  This allows, e.g., x_insert_selection to be bound to a key.
27. src/indent.c: Added support for a second string character to the
    syntax tables.  This improves the highlighting of, e.g., python
    code which uses two string characters.
28. lib/pymode.sl: minor cleanups.
29. src/wterm.c, w32cons.c: make NumLock return ESC O P when
    NUMLOCK_IS_GOLD is set.  Hopefully EDT emulation will now work
    properly on win32 systems.
30. src/menu.c: Ctrl-G causes abortion of menu mode.
31. src/wterm.c: drag/drop functionality for wjed
    ("John Skilleter" <john@skilleter.org.uk>)
32. lib/html.sl: updated to support euro, etc.
    (Kees Serier <Kees.Serier@ordina.nl>)
33. src/win32.c:w32_pclose: add a work-around to what may be a Borland
    compiler bug. ("John Skilleter" <john@skilleter.org.uk>)
34. src/xterm.c: internal border width of the of xjed window is now
    configurable via -ib xjed option (Jim Clifton <clifton@brandeis.edu>)
35. lib/krconv.sl: respect the value of C_BRA_NEWLINE
    (Ulrich Bernert <bernert@planet.de>)
36. src/buffer.c,ledit.c: If a file is read through a symbolic link,
    set the name of the buffer to the name of the symlink and not the
    actual file.  This is allows e.g., foo.c --> /dev/c/0013
    to be interpreted as a C file.
37. src/win32.c: differentiate between (shift|alt|ctrl)-backspace
    (John Skilleter <john@skilleter.org.uk>)
38. src/cmisc.sl: Make c_end_of_function symmetric with
    c_top_of_function.  (Reuben Thomas <rrt@dcs.gla.ac.uk>)
39. src/wterm.c: fix problem with calculation of font-height for wjed.
    Also added new intrinsic for setting the font: w32_select_font
    (John Skilleter)
40. New internal hooks added: _jed_before_key_hooks, _jed_after_key_hooks
41. lib/wmark.sl: rewritten to use _jed_before/after_key hooks.  The
    result is that one is now able to use the regions with menu and
    minibuffer commands.
42. lib/popups.sl: Edit menu enhanced with more region functions.
    Register functions moved to region functions popup.
43. src/menu.c: disabled access to the menus from the minibuffer
44. lib/cmode.sl: added mode-specific menu entries to list all
    functions and macros defined by the file.  This affects C mode and
    SLang mode.
45. New intrinsics: exit, _exit.  These are useful in jed scripts to
    return an exit value to the shell.  exit is like exit_jed and
    _exit is like quit_jed except an argument is required.
46. lib/tmmode.sl: This file implements the tm_mode for editing
    text-macro files.  In addition, the text-macro processing code
    (textmac.sl) was removed from the jed distribution as well as
    lib/tm/*.  Instead, the text-macro processing code and macros will
    be made available as a separate package.
47. src/sig.c: Changed the way SIGHUP and SIGTERM are handled to avoid
    a possible race condition.
48. lib/latex.sl,ltx-math.sl: If another tex file was loaded while
    latex math mode was active, then latex_math_mode would cease to
    work in the first buffer.  This has been fixed.
49. lib/perl.sl: Updated to Mark Olesen's latest version.  See
    lib/perl.sl for details.
50. lib/sccs.sl: New file supporting SCCS revision control (Philip
    Brown).
51. src/intrin.c: New intrinsic function: run_program.  This plays the
    same role as the "system" function except jed resets the display
    first, if run in a terminal.  For X, it runs the specified program
    in another xterm, or the terminal set by the XTerm_Pgm variable.

    *** Note: This function needs to be fixed to work asynchronously
              on win32.  Any volunteers??

52. src/xterm.c: Added Charl Botha's XRENDER patch to Xjed.
53. lib/ide.sl: Remove references to ide_function_help (Guido Gonzato).
54. lib/site.sl: save_buffer was not calling read_file_from_mini
    without a prompt string <klaus.schmid at kdt.de>
55. doc/tm/*.tm: removed docs for obsolete functions <klaus.schmid at kdt.de>
56. lib/mouse.sl: wheel mouse was not ignoring hidden lines 
     <klaus.schmid at kdt.de>
57. lib/f90.sl: Merged fix and free formats into the same file.  In
    addition to f90_mode, there is now f90_fixed_format_mode and
    f90_free_format_mode.  The default format for f90_mode is "free",
    which may be set via the F90_Default_Format variable.
58. lib/registers.sl: rewritten to allow registers to be given
    meaningful names by the user.  Also, fixed limit of 95 registers
    removed.  
59. lib/folding.sl: Fixed endless loop during a call to
    fold_whole_buffer when a fold-start mark is at the end of the
    buffer.  Several other tweaks aimed at preserving the current
    position when closing folds (klaus.schmid at kdt.de)
60. lib/edt.sl: multiple definition of exit corrected
      (joukj at hrem.stm.tudelft.nl (Jacob (=Jouk) Jansen))
61. lib/search.sl,isearch.sl: If the search string contains any upper case
    characters then a case-sensitive search will be performed.
62. src/mkfiles/makefile.all: Add CFLAGS macro to MINGW32/CYGWIN32
    section. Miquel Garriga <miquel at icmab.es>
63. src/screen.c: Make the [EOB] line read-only. Miquel Garriga <miquel at icmab.es>
64. src/version.c: Use __MINGW32_VERSION if defined to get the
    compiler version. Miquel Garriga <miquel at icmab.es>
65. lib/os.sl: make sure W32shell_Perform_Globbing is declared. Miquel Garriga <miquel at icmab.es>
66. lib/cal.sl: avoid interpretation of 08 in dates as octal. Miquel Garriga <miquel at icmab.es>
67. src/screen.c: %F may be used to specify complete pathname on the
    mode-line. (John Skilleter).
68. doc/tm/keys.tm: get_key_binding documentation corrected. (Klaus
    Schmid <klaus.schmid at kdt.de>)
69. src/mkfiles/makefile.all: Make sure CFLAGS defines JED. Also add
    support for creating wjed in cygwin environment (Paul
    Shirley).
70. New intrinsic: expand_symlink expands symbolic links


{{{ Previous Versions 

Changes since B0.99-14 {{{

1. lib/site.sl: if $HOME/.jedrc does not exist, then load jed.rc from
   $JED_LIBRARY.  This did not work in 0.99-14.
2. lib/cmode.sl: Use double quotes when calling c_set_style_hook.
   (Marko Mahnic <mmarko.dfg@moj.net>).
3. src/abbrev.c:what_abbrev_table: A misplaced return statement
   prevented it from returning information regarding the global table.
   (John Skilleter <John.Skilleter@pace.co.uk>).
4. lib/cmode.sl: modify in_class function to allow template classes.
5. lib/cmode.sl: modify c_set_style to account for C_Class_Offset.
6. lib/compile.sl: tweak RE for VC++ 6 and add RE for RGBE gameboy
   assembler (Paul Shirley" <pauls@climax.co.uk>).
7. lib/cmode.sl: Handle multiple // in // style comments.
8. src/userinfo.c(get_username_info): avoid NULL ptr deref if getpwuif
   fails.
9. lib/ashell.sl: try_builtin was returning -1 upon failure instead of
   cmd.
10. src/pty.c: use openpty when available (Diego Roversi
    <diegor@tiscalinet.it>).
11. src/indent.c: Ignore the quote character when looking for the end
    of a comment.
12. lib/info.sl: Avoiding locking the info file when in a read-only
    directory.
13. src/keymap.c: Make sure to call switch_active_buffer_hooks after
    the startup_hooks have been run.
14. lib/latex.sl: updated for newer latex info files
    (harpend@xmission.com).

20. src/intrin.c: set_color intrinsic renamed to _set_color.
    set_color is now a slang function that calls _set_color.  The idea
    is to allow one to overload set_color with something more
    sophisticated, e.g., one that exploits a color name database
    (rgb.txt).

Changes since B0.99-13 {{{

1. lib/chglog.sl: tweak date format (Peter Wang <tjaden@psynet.net>).
2. Xjed would crash whenever 'set_abort_char' was called.  This
   affected ide and wordstar modes.
3. screen.c: enable syntax highlighting by default.
4. src/Makefile.in: support for $CPPFLAGS added
5. src/Makefile.in: DESTDIR support added by Brad <brad@comstyle.com>.

8. QNX-specific patches from Tijs Michels <tijs@vimec.nl>.
9. Typos corrected in VMSMAKE.COM by Jouk Jansen
   <joukj@hrem.stm.tudelft.nl>.
10. updated ide.sl, docbook.sl, and rcs.sl from Guido Gonzato.
11. New function unset_ctrl_keys that unsets keys ^A-^Z.  This is
    better than calling unsetkey for ^K, ^X, etc.
12. Default value for Jed_Highlight_Cache_Path initialized from
    'get_jed_library_path' instead of JED_ROOT/lib.
13. lib/comments.sl: get_comment_info changed to return NULL upon failure.
14. src/wterm.c: Several places where buffer overflows could happen
    were fixed.
15. If c_set_style_hook is defined, it will be called to allow the
    user to define custom styles.
16. src/wterm.c: support for wheel mouse added by John Skilleter
    <John.Skilleter@pace.co.uk>.
17. src/wterm.c: small fix for NumLock GOLD key emulation courtesy of
    Nick Tatham <nick.tatham@pobox.com>.
18. lib/shell.sl: shell function now calls shell_mode_hook.
19. lib/occur.sl: add 'bob' to find all occurances in the current
    buffer. (Reuben Thomas <rrt@dcs.gla.ac.uk>)
20. lib/texcom.sl:  Allow lines that start with \ to be in the middle
    of paragraphs unless the line starts with \begin, \end, or \item.
    (Reuben Thomas <rrt@dcs.gla.ac.uk>)
21. New function to signal the foreground process group of a
    subprocess: signal_fg_process.  lib/ashell.sl modified accordingly.
22. src/file.c: Set the buffer creation time associated with a file to
    the file modification time.  This avoids problems with broken
    software that set the modification time to the future.
    (John Skilleter <john.Skilleter@pace.co.uk>)
23. Warn user if an attempt is made to modify a buffer whose file is
    read-only.
24. lib/site.sl: new variable: Jed_Home_Directory.
25. _jed_startup_hooks added.  These hooks are called prior to going
    into editor's main loop.  This replaces jed_startup_hook.
26. Menu_Load_Popups_Hook variable replaced by the "load_popup_hooks"
    chain.  Instead of using:
        variable Menu_Load_Popups_Hook = &some_function;
    use, e.g.,
	append_to_hook ("load_popup_hooks", &some_function);
27. New intrinsic function: _jed_run_hooks, which will run the hooks
    in a hook chain.
28. src/ledit.c: Make sure that JWindow is non-NULL in flush_message.
29. src/menu.c: Support Simulate_Graphic_Chars on DOS/WINDOWS.

    bibtext.sl) Lutz Donnerhacke <lutz@iks-jena.de>.
33. src/search.c:regexp_nth_match: if passed 0, return the whole match
    as documented.
34. src/ledit.c: work around a slang bug triggered by jed that
    prevents the use of #ifeval expressions.
35. Support for hook called "keybindings_hook".  See doc/txt/hooks.txt
    for more information.
36. Keyboard macros were stopped if a slang function triggered an
    error that was subsequently cleared via an ERROR_BLOCK.  Now, such
    macros will continue to execute.
37. lib/mouse.sl: new variable: Mouse_Wheel_Scroll_Lines.  This
    variable may be used to customize the number of lines that are
    scrolled when using the wheel. (Default is 3).
38. lib/ashell.sl: filename completion added.
39. lib/comments.sl: Avoid adding whitespace to the end of lines if a
    comment does not have an end-comment string (Guenter Milde
    <G.Milde@physik.tu-dresden.de>).
40. lib/os.sl: wjed.exe can now use jed's text menus instead of the
    native GUI menus.  At the moment, the text menus are far more
    functional than the native menus.  Uncomment the appropriate line
    in lib/os.sl to use the text menus.

Changes since B0.99-12 {{{

0.  Important Notes:
    
 a) If you are not using set_color_scheme to set colors, you may find
    that your color settings will not work.  Now, if the user does not
    call set_color_scheme, it will automatically be called with
    _Jed_Default_Color_Scheme.  If you do not want this feature, set
    _Jed_Default_Color_Scheme to NULL after setting your colors.

 b) All keybindings prefixed with ^C were removed from lib/*.sl and
    replaced by calls to functions such as definekey_reserved.  The
    idea is that each emulation (emacs, ide, etc), is to reserve
    prefix key that may be used by various modes for binding.  As an
    example, folding.sl used to contain lines such as:

       local_setkey ("fold_whole_buffer", "^C^W");

    This made this mode and others fundamentally at odds with
    emulations that use ^C for something else, e.g. the ide emulation.
    Now, lines such as the above have been changed to:

       local_setkey_reserved ("fold_whole_buffer", "^W");

    Of course the emacs emulation preserves the ^C key for extension
    in this way, which means that the two lines are equivalent.  
    
    The interface to this ``reserved'' key prefix includes the
    following functions:
    
       setkey_reserved
       unsetkey_reserved
       local_setkey_reserved
       local_unsetkey_reserved
       definekey_reserved
       undefinekey_reserved

     and have the same calling syntax as similar functions without the
     reserved suffix.  The variable specifying the reserved key prefix
     is called _Reserved_Key_Prefix, whose value will depend upon the
     emulation:
     
         emacs: ^C
	 ide:  ^Z

1.  src/VMSMAKE.COM: typo corrected (joukj@hrem.stm.tudelft.nl).
2.  lib/textmac.sl: del(2) --> deln(2)  (affects processing of {})
3.  lib/cmode.sl: New variable C_Switch_Offset controls indentation in
    a switch statement.
4.  cua.sl added to the distribution.
5.  provide/require functions added.
6.  If ^G pressed in mini-buffer, make sure mode-dependent menubar is
    restored.
7.  Avoid file-changed-on-disk problems associated with a failed write
    to disk.
8.  src/file.c: VMS specific problem writing to a new file on OpenVMS
    fixed by joukj@hrem.stm.tudelft.nl.
9.  src/ledit.c: Regard a library file beginning with ../ as relative to the
    current dir.  That is, `jed -l ../file.sl' will load the obvious
    one.
10. Signal an error if the insert intrinsic fails.
12. lib/pymode.sl: small patch from jimbag@kw.igs.net to close the
    output window if it is empty.
13. src/main.c: If unable to get the current working directory upon
    startup, chdir to / and assume that (Pascal Haakmat
    <a.haakmat@chello.nl>).
14. DECCMAKE.COM removed from the distribution--- it is not needed.
15. Color_Scheme_Path variable added.  This is a comma-separated list
    of directories to search for color schemes.
16. lib/info.sl: subtle bug fix involving search for split files
17. doc/txt/slangfun.txt dropped from the distribution since it is
    distributed with slang.
18. lib/help.sl: A patch from Guenter Milde
    <G.Milde@physik.tu-dresden.de> to provide some help on internal
    functions.
19. lib/verilog.sl: updated keywords provided by Kikutani Makoto
    <kikutani@sprintmail.com>.
20. lib/comments.sl: new functions to support commenting lines/regions
    provided by Guenter Milde <milde@physik.tu-dresden.de>.
21. src/w32cons.c: Support for AltGR added by Juha Ruotsalainen
    <Juha.Ruotsalainen@nokia.com>.
22. src/keymap.c: Default keybinding of " and ' keys changed from
    text_smart_quote to self_insert_cmd.
23. Additional command line options added: -help, -a, and -e.  Run
    'jed -help' for more info.
24. New modes: docbook (Guido Gonzato); php (Mikael Hultgren
    <mike@yeah.nu>).
25. Updated lib/rcs.sl, backups.sl (Guido Gonzato)
26. lib/compile.sl: support for column info added by Lutz Donnerhacke
    <lutz@iks-jena.de>.
27. Xjed: Support for wheel mice added by Daniel Serpell
    <daniel@mat.utfsm.cl>.
28. lib/keydefs.sl tweaked by GM <g.milde@physik.tu-dresden.de>.
29. src/wterm.c: Added Nick Tatham's <nick.tatham@peramon.com> NumLock
    patches for EDT emulation.
30. If Xjed cannot open the display, it will revert to jed and use the
    terminal. (Thomas J. Moore <dark@mama.indstate.edu>).
31. Updated perl.sl from Mark Olesen <molesen@zeunastaerker.de>.
32. lib/shell.sl: do_shell_cmd now accepts an optional argument (G. Milde
    <guenter@Ptprs1.phy.tu-dresden.de>)
33. lib/register.sl: Updated by Francesc Rocher <f.rocher@computer.org>.
34. lib/iso-latin.sl: word definition tweaked by Thomas Henlich
    <henlich@mmers1.mw.tu-dresden.de>.
35. tweaks to src/mkfiles/makefile.all from John Skilleter
    <John.Skilleter@pace.co.uk>.
36. src/wterm.c: Recognize Shift-TAB (Paul Shirley
    <paul.shirley@ntlworld.com>).
37. lib/minued.sl, lib/history.sl updated by Francesc Rocher.
38. New function: c_set_style: this may be used to set the C
    indentation style to one of several popular styles, e.g., "GNU",
    "k&r", "BSD", "linux", and of course "jed".
39. src/unix.c: filename completion now supports globbing on Unix
    systems, e.g., completion on *.c returns files that end in *.c.
    (Olly Betts <olly@survex.com>)
40. If a mode cannot be found for a filename extension 'ext', but
    'ext_mode' exists as a function, then use it.
41. Support for DFA syntax highlighting enabled by default.  The names
    of the DFA-specific intrinsic functions have been prefixed by
    "dfa_".  Now the user can turn on/off dfa syntax highlighting for
    any mode via any of the new functions:
    
           use_dfa_syntax
	   disable_dfa_syntax_for_mode  
	   enable_dfa_syntax_for_mode
    
    Finally two new variables control the search for DFA cache files:
    
      	  Jed_Highlight_Cache_Dir
          Jed_Highlight_Cache_Path	 
42. Unix: /etc/jed.conf or /usr/local/etc/jed.conf may be used in
    place of $JED_ROOT/lib/defaults.sl --- See INSTALL.

    a. sysdep.c:pcsystem_getdisk: correct typo and use getdrive with
       BCC.
    b. wterm.c: avoid infinite loop when parsing command line
       containing quotes.
6. Tweak to avoid locking file during narrow/widen operations
7. lib/info.sl: If searching a file via grep for -SOMETHING, then
   escape the `-' with \.
8. Patch from Nick Tatham <nick.tatham@lexicos.com> to build wjed.exe
   with VC.
10. Documentation reorganized and Guido's reference guide has been added.
11. lib/info.sl: Add support for bzipped files (Guido Gonzato).
12. _jed_switch_active_buffer_hooks added.  These hooks are called whenever
    one switches active buffers.
13. src/xterm.c: If pasted text starts with ESC(B, then assume it is
    ISO2022 encoded.
14. Bug-fix made to allow two or more menubars to co-exist.  This was
    never tested until recently.
15. text.c: bug fixed when wrapping paragraphs that contain lines
    indented beyond the wrap column.
16. Bug involving xform_region fixed.
17. Internal function `save_buffers' renamed to `save_some_buffers' to
    avoid name conflict with slang function `save_buffers'.
18. lib/site.sl: save_buffer function modified to work on buffers with
    no associated filename.
19. src/lock.c: If running in batch mode and a file is locked, then
    treat it as so.
20. lib/textmac.sl: support for passthru environments added.
21. lib/shell.sl restructured.  Now, `do_shell_cmd' with a prefix
    argument will use the current buffer for its output.  Note that the
    shell_perform_cmd function now requires 2 arguments.
22. lib/pushmode.sl: push_mode can now take an optional argument.
23. src/indent.c: Make sure lines containing repeated perl-style
    comment characters are recognized as comments.
24. lib/mousex.sl: make sure value of META_CHAR does not affect mouse
    input.
25. lib/html.sl: reference to "?help" removed.
26. abbrev.sl: set_abbrev_mode function was not calling
    _set_buffer_flag properly.
27. New color scheme: blue3.sl, also win1250 and dos852 character
    tables (PPrikryl,Petr <PRIKRYLP@skil.cz>)
28. CUA-like keybindings added (Reuben Thomas <rrt1001@cl.cam.ac.uk>).
29. New file: keydefs.sl.  This defines symbolic constants for many
    function keys.  I modified ide.sl and wmark.sl to use it.
30. sysdep.c: small patch for compiling on OS/2 (Michael Muller
    <mmuller@enduden.com>)
31. Small mis-feature corrected by Olly Betts <olly@survex.com>
    involving combination of forward and backward yp_* functions.
32. Xjed specific pastel color scheme added (Frank Klemm
    <pfk@fuchs.offl.uni-jena.de>)
33. Xjed-specific color scheme directory added.  Use, e.g.,
        set_color_scheme ("Xjed/pastel0");
34. lib/cal.sl internationalized by Tamminen Eero
    <t150315@students.cc.tut.fi>.
35. lib/emacs.sl: forward/backward_paragraph bindings added.

}}}

Changes since B0.99-10 {{{ 

   0.  Important backward-incompatible changes:

     a.  Compiler interface simplified.  New functions include:
           compile_select_compiler
	   compile_add_compiler
         The variables `compile_parse_error_function' and
	 `compile_parse_regexp' are nolonger used.  Use
	 Compile_Default_Compiler instead.  The default is "gcc".
	 See doc/compile.txt for more information.
     b.  slang version 1.3.11, or later is required.  If you have not
         already done so, then it is a good idea to upgrade to 1.4.1.
     c.  get_key_function replaced by get_key_binding, which is more
         versatile.

   1.  TeX/LaTeX modes: Automatic conversion of ... to \dots
       suppressed in verbatum environments.
   2.  xjed: --debug-xjed command line argument added.  Currently,
       this does very little but may prove useful.
   3.  lib/chglog.sl added.  This gives jed the ability to maintain
       ChangeLog files.  The default binding for the
       `changelog_add_entry' function is "^X4a" (for consistency with
       emacs).
   3.  lib/rcs.sl modified.
   4.  Several lib/*.sl files were modified to use high-level
       functions to set buffer flags instead of setting them directly.
   5.  New intrinsics:

          set_username (String_Type);
          set_realname (String_Type);
          set_hostname (String_Type);
	  String_Type get_username ();
	  String_Type get_realname ();
	  String_Type get_hostname ();
       and slang functions:
          set_emailaddress (String_Type);
          get_emailaddress (String_Type);
   6.  Emacs-style file locking added (see doc/filelock.txt).
   7.  Changes made to jed/src/file.c to avoid possible race
       conditions in a multi-user environment. (Colin Phipps
       <crp22@cam.ac.uk>).
   8.  Some cleanup involving expand_filename and expand_link.
   9.  ctags.sl modified.
  10.  If `global_mode_hook' exists, it will be called after calling
       the mode hook.  This function will be passed the name of the
       mode hook.
  11.  To implement 10, calls to `runhooks' in mode-setting functions
       were replaced by run_mode_hooks.
  12.  jed --version displays compile-time features.
  13.  `insert' intrinsic can now insert binary strings (those with \0).
  14.  If an expansion for an abbreviation ends in \010, then the
       expansion will be performed but the character causing the
       expansion will not be inserted.  In addition to this feature,
       arbitrary limits were removed from src/abbrev.c
  15.  Directory name that shell command will run in is displayed as
       part of the shell command prompt.
  16.  pymode.sl updated to v1.3.
  17.  On command line, files such as a//b/c are replaced by a/b/c.
  18.  Avoid infinite loop when using query_replace_match to replace ^$ 
       with nothing.
  19.  If using slang 1.4.1+ use strreplace in str_replace_all.
  20.  matlab.sl: matlab_mode function was accessing $1 variable.
  21.  Two eol-type comment styles now supported.  For example,
       matlab_mode defines both `#' and `%' as comments.  It should
       now be possible to have comments such as `REM', which should be
       familiar to BASIC programmers.
  22.  src/pty.c: Allow an ioctl to silently fail if `ttcompat' does
       not exist as a stream module. (Diego Roversi
       <diegor@tiscalinet.it>)
  23.  lib/cmode.sl: C_Class_Offset variable added to allow the
       specification of indentation withing a class definition.
       (Kumaran Santhanam <kumaran@alumni.stanford.org>)
  24.  src/unix.c: BeOS support added by Eddie Penninkhof
       <wizball@xs4all.nl>.
  25.  macro.sl: bug fix involving use of an unitialized variable in
       macro_to_function.
  26.  lib/pymode.sl: make python keywords case sensitive (Simon
       Tatham <anakin@pobox.com>).
  27.  xterm.c: If a window is uncovered the xterm.c current color
       could become out of sync with vterm.c color. (Simon Tatham
       <anakin@pobox.com>).
  28.  lib/digraph.sl: DOS specific patch from
       G.Milde@physik.tu-dresden.de (G. Milde).
  29.  src/rgrep.c: example for finding repeated words corrected
  30.  doc/tm/rtl/color.sl: keywordN added to set_color doc
  31.  erase_buffer function checks read-only status of buffer
  32.  set_process intrinsic modified to accept function references.
  33.  Bug in translate_region fixed.
  34.  New menu_insert_* intrinsic functions from James Telfer
       <James@Telfer.com>.
  35.  Bug in re_search_forward fixed involving non-RE search pattern.
  36.  iso2xxx.sl: replace strncat by strcat.
  37.  setbuf_info: If this is used to rename a buffer to one that
       already exists, then a unique name will be generated (e.g., xxx
       -> xxx<1>).
  38.  New hooks facility that allows one to attach hooks to the
       following internal hook lists:

        _jed_append_region_hooks
	_jed_exit_hooks
	_jed_find_file_after_hooks
	_jed_find_file_before_hooks
	_jed_init_display_hooks
	_jed_insert_file_hooks
	_jed_quit_hooks
	_jed_read_file_hooks
	_jed_reset_display_hooks
	_jed_resume_hooks
	_jed_save_buffer_after_hooks
	_jed_save_buffer_before_hooks
	_jed_set_mode_hooks
	_jed_suspend_hooks
	_jed_write_region_hooks

       See doc/hooks.txt--- especially if you have created
       (non-mode related) hooks.
  39.  lib/compress.sl: This implements a new function called
       `auto_compression_mode' that uses the new hooks facility to
       automatically compress/decompress files.
  40.  Additional slang intrinsics made available to the editor:
       stdio, posix_io, and ospath.
  41.  custom_variable function added to site.sl.  This function is
       due to Francesc Rocher <rocher@golem.udg.es>.
  42.  Patches from Jim Knoble <jmknoble@pobox.com>:
          Xjed: set group_leader WM hint and WM_COMMAND property.
	        Add drag threshold for ButtonPress/Release events
	  menu.c: Add menu_selection_char color for additional control
	        of menu items.
  43.  Patches from John Skilleter <skilleter@btinternet.com>:
          win32: 
	     Allow command line arguments with spaces by removing
	       quote characters.
	     Attach Drive letter to filenames without one.
	  Extra control over status line: 
	    * %O - Overwrite/Insert flag - like %o, but shows INS/OVR
	    * %l - Line number           - shows current line number
	    * %L - max line nmber        - shows number of lines in the file

  44. Added history.sl and minued.sl from Francesc Rocher
      <rocher@golem.udg.es>. history.sl uses _jed_exit_hooks to
      save/recall minibuffer history.  See lib/history.sl for more
      information.

  45. Xjed: Cut/paste fixed to work with programs that do not support
      COMPOUND_TEXT selections (gnome, kde, ...).
  46. The maximum length of a keyword has been increased to 48
      characters.  In a later release, the limit will be removed.
  47. If C_Autoinsert_CPP_Comments is non-zero, and if a line starts
      with // style comments, newline_and_indent will insert // on the
      next line.
  48. unix.c: when saving a file, try to preserve uid of file instead
      of using uid of process (Thomas Henlich
      <henlich@mmers1.mw.tu-dresden.de>).
  49. Updated perl_mode from Juho Snellman <jsnell@iki.fi>.  This
      version included a routine for indenting perl; however, it is
      disabled by default.
  50. New syntax flag bit: 0x80.   This indicates that strings do not
      span multiple lines.
  51. getbuf_info/setbuf_info may be given an optional argument to
      work with any buffer.
  52. New intrinsic: copy_keymap.  This creates a new keymap by
      copying another.
  53. In text-mode, TAB is bound to the new function text_indent_relative.
  54. wmark.sl tweaked.
  55. win32 console version: Fixed problem with ENHANCED keys.

}}}

Changes since B0.99-9 {{{ 
   1.  perl.sl: (=head,=cut) regarded as comment begin/end pairs
   2.  java.sl: syntax for // comments added.
   3.  menu_set_menu_bar_prefix intrinsic added to allow one to change
       the menu prefix string ("F10 key ==> ").
   4.  edt.sl: better emulation of EDT scroll regions (Ulli Horlacher
       <framstag@moep.bb.bawue.de>).
   5.  Calling `recenter' will not force an immediate screen update.
   6.  shmode.sl: Extra keywords added (Ulli Horlacher
       <framstag@moep.bb.bawue.de>).
   7.  isearch.sl: Function/Arrow keys will also terminate search
   8.  Updated ide.sl mode from Guido Gonzato
       <guido@ibogeo.df.unibo.it>.
   9.  Various patches from Charl Botha <cpbotha@ieee.org> affecting
         bibtex.sl, latex.sl, and site.sl.
  10.  modeinfo.sl rewritten to use an associative array.
  11.  xterm.c: ignore ConfigureNotify event if the window size does not
       change (Charl Botha <cpbotha@ieee.org>).
  12.  `unsigned short' replaced by `SLsmg_Char_Type'.  More work will
       have to be done when version 2.0 of slang comes out with
       unicode support.
  13.  Change Buffer menu item added.  This required a new intrinsic
       function: menu_set_select_popup_callback
  14.  Documentation updates and redundant documentation removed from
       C files.
  15.  Whitespace in front of C preprocessor constructs ignored via
       new `set_syntax_flags' bit.
  16.  Documentation changed to reflect the fact that vinsert does not
       require the number of items.  Similarly, the .sl files were
       modified accordingly.
  17.  process_query_at_exit intrinsic added.
  18.  If DOLLAR_CHARACTER is 0, no such character will be used as an
       indicator that text extends beyond the borders of the window.
  19.  New inrinsics: _get_point, _set_point.  These should be used in
       favor of the POINT variable which will be removed from future
       releases.
  20.  win32: all intrinsic win32 menu functions have been renamed
       with a `w32_' prefix, e.g., redraw_menubar --> w32_rename_menubar.
       Hopefully, this change will not affect anyone.
  21.  `directory' function is no longer an intrinsic function.  Now
       it is a slang function simulated using the listdir intrinsic.
  22.  win32, msdos, OS/2: New variable: Case_Sensitive_Filenames
       If non-zero, filenames will be treated as case-sensitive on
       these systems, otherwise filenames will be considered as
       case-insensitive.  This change was patterned on a patch from
       Eddie Penninkhof <wizball@xs4all.nl>.

Changes since B0.99-8 {{{ 
   0.  Miscellaneous patches from Ricard Sierra <irebulle@nexo.es>
       added.  (Note: this item was added on Nov 17, 1999)
   1.  win32: define_color intrinsic was not working properly because
       of an old-style definition.
   2.  win32: g32shell.exe performs globbing on command line
       arguments but w32shell.exe does not.  To use the globbing
       shell, put `W32shell_Perform_Globbing=1;' in your jed.rc file.
   3.  win32.c: bug in sys_findnext corrected.
   4.  problem with enable_menu_keys on win32 fixed.
   5.  doc/script.txt updated.

       autoconf install script.
  12.  Improved detection of fold marks.  
  13.  win32 patch involving read-only files from John Skilleter
       <john.Skilleter@pace.co.uk>.
  14.  update_sans_update_hook intrinsic added.
  15.  win32: bug involve handling of ALTGR fixed.  In addition, several
       other changes were made to the win32 keyboard code to allow ^G to
       interrupt a slang procedure, e.g., while(1);
  16.  If an interactive seach finds a match on a hidden line, e.g.,
       one in a fold, then the line will be made momentarily visible.
   (B0.99-9 released)
  17.  win32: Ctrl-2 was not generating the correct keysequence.
   (B0.99-9a released)

}}}

Changes since B0.99-7 {{{ 
   0.  win32 subprocess support changed.  Basically from what I
       consider to be bug in windows, a helper application is required
       to launch subprocesses (jed/bin/w32shell.exe).  Microsoft says
       this need is due to ``differences'' between windows 95, 98, and
       NT (???!!!).  A function `_win32_get_helper_app_name' has been
       added to allow some experimentation with the helper app.  In
       addition, the console version will spawn a subshell when
       suspending.

   1.  Under Unix, if `info' is a symbolic link to jed, then jed will
       run as an info reader.
   2.  If you attempt to write to a file that has changed on the disk,
       you will be warned.
   3.  Asynchronous process denied if started via `jed -secure'
   4.  A warning message is printed if compiled against a version of
       slang that is more recent that the one it is linked to--- this
       happens when the user does not properly install the slang library.
   5.  OS/2 findfirst/findnext patch from Eddie Penninkhof
       <wizball@xs4all.nl>.

  13. enable_menu_keys added to make the menu-bar hotkeys work after
      loading an emulation that redefines the keys, e.g., ESC-f in
      emacs.sl.
  14. DISPLAY_EIGHT_BIT semantics changed to match those of the SLsmg
      screen management routines.
  15. SELECTIVE_DISPLAY variable removed.
  16. enable_xmouse function added to facilitate loading of mousex.sl when
      running jed in an Xterm.

Changes since B0.99-5 {{{ 
   0.  New drop down menu system added.  These menus work in all
       versions of jed and may be activated via the F10 key or via the
       mouse.  For use in an xterm, load mousex.sl.  See doc/menus.txt
       for more information.

       For example, a mode can define folding information that
       folding.sl can use.  See, e.g., folding.sl and cmode.sl.
       
  (B0.99.1 snapshot released)
  24.  Bug fixes:
       * Blink match bug fixed involving " at the beginning of a line.
       * In sh-mode `\'' given a string syntax.
  25.  hook_add_to_hook replaced by hooks.sl:hook_add_hook.  I believe
       this interface permits better chaining of hooks.
  26.  isearch.sl bug fix involving ^G abortion of search.
  27.  Updates to dabbrev.sl to use array syntax.  Also foreach...using
       used in some .sl files.  See slang documentation for
       information about foreach construct.
  28.  Some functions and variables in several lib/*.sl files have
       been made `static'.

----- snapshot jed0.99_981116 made available (B0.99.2) -----

  29.  Microsoft Visual C support added to compile.sl
       (Paul Shirley <Paul@chocolat.foobar.co.uk>).
  30.  Small patch to mouse.c that fixes a bug in the presence of
       folded text.
  31.  Tweak to shmode.sl
  32.  On black and white terminals, message lines are nolonger
       displayed with attributes.
  33.  Tweaks to xjed display to correct a bug on maximization of the
       window.
  34.  OS/2 Subprocess support provided by Kazuhisa Yoshino
       <k-yosino@inatori.netsweb.ne.jp>.
  35.  showkey for ``eight-bit'' character now displays the character
       properly.
  36.  Under SVR4 unix, pty implementation changed to use stream
       modules instead of BSD pty emulation.  This was necessary
       because Solaris 2.6 and 2.7 have buggy BSD pty emulation and
       jed was able to crash those operating systems.
  37.  New modes from Guido Gonzato <guido@ibogeo.df.unibo.it>:

         ide.sl : 99% compatible Borland IDE mode (see doc/ide-mode.txt)
	 sgml.sl
	 rcs.sl
	 matlab.sl
	 backups.sl : Make numbered backups

  38.  __BORLANDC__ specific patches from John Skilleter
       <skilleter@zetnet.co.uk>.
  39.  MAIN_ARGC replaced by __argc and command_line_arg replaced by
       __argv.
  40.  Tweaks to c_format_paragraph

  41.  New MSWINDOWS vaiable from John Skilleter: FN_CHAR
       Normally, function keys generate a two character sequence: ^@
       (ascii 0) followed by some other character (see
       doc/pc-keys.txt). This variable makes ^@ configurable.  The
       default is 0 (^@).
       
  42.  Documentation of library functions available online and via
       doc/libfuns.txt.
       
  43.  Use of strchop and strchopr modified according to new semantics.

  44.  mkdir and rmdir intrinsic functions were replaced by slang
       library intrinsics.
       
  45.  unix_kill function changed to `kill' (S-Lang library change).
  
  46.  textmac.sl modified to use associative arrays.

------B0.99.4 snapshot released ------------

  47.  Improved Xjed selection support and internationalization
       support from Kazuhisa Yoshino <k-yosino@inatori.netsweb.ne.jp>.
       
  48.  iso-lat3.sl added (Byrial Jensen <byrial@post3.tele.dk>).
  
  49.  It is now possible to set dabbrev's word characters on a mode
       via:
       
         mode_set_mode_info ("C", "dabbrev_word_chars", "a-z_0-9A-Z");

  50.  Improved python mode submitted by Tom Culliton
       <culliton@clark.net>.

  51.  nick.tatham@pobox.com provided a work-around for a windows 95
       bug in the rename function affecting long filenames.

  52.  Wrap bug involving a long line of non-whitespace characters
       fixed.
       
  53.  Makefile install target fixed.
  54.  Additional highlighting of ANSI/ISO C++ keywords courtesy of
       Ragnar Hojland Espinosa <ragnar@redestb.es>.
  55.  Windows specific patch from cpbotha@bigfoot.com that fixes a
       NULL pointer dereference in cover_exposed_area.
  56.  Bug fixed involving the free_narrow function.  Also, dabbrev.sl
       uses widen_region instead of widen.
  56.  If buffer does not exist on disk, and is not modified, then
       file_changed_on_disk will return 1.
  57.  Misc bug-fixes: ()=insert() in sendmail.sl, blink bug in
       indent.c.
  58.  If a file contains hard links, a backup is made via copying.
  59.  Misc patches from Marcin 'Qrczak' Kowalczyk"
       <qrczak@knm.org.pl>: html typo and changes made to xkeys.c for
       better EDT emulation by Xjed.
  60.  set_prefix_argument intrinsic function added and changed made
       to the emacs_escape_x function to preserve a prefix argument.
  61.  compile function modified to accept an optional string
       argument to specify the command to run.  If the argument is not
       present, then the user will be prompted for the command.
  62.  Buffer-local variables modified to allow any slang data type.
       The function `create_blocal_var' nolonger accepts a `type'
       argument.  Also a new intrinsic `blocal_var_exists' was added.
       This change was suggested by Lucho Ionkov.
  63.  jed --version prints version number.
  64.  A workaround for a Sun cmdtool bug.  That terminal is a real
       loser.
  65.  Configure indicates that linux has `grantpt', which indicates
       that it has SysV ptys but it does not.  BSD pty support forced
       for linux.  This was the reason that subprocess support failed
       to work with 2.2 kernels.

  66.  New function: `set_color_scheme (name)'.  This will allow a user
       to select a predefined color scheme.  See jed/lib/colors/README.

   4.  wmark.sl: mods to use display_hook (Marius Groeger <mag@sysgo.de>).
   6.  OS/2 and Windows patches

}}}

Changes since 0.98-4 {{{ 
   0.  MAJOR changes to the slang language.  It is now MUCH more
       powerful and flexible.  However, there is a price to pay since
       some functions changed.  See slang documentation for full
       details.  Also look at slang/UPGRADE.txt for more information
       about upgrading your slang functions.

       Important changes include that may affect user functions include:
       
         vmessage and verror now work like:
            vmessage ("%s-%s", "hello", "world");
         instead of
            vmessage ("%s-%s", "hello", "world", 2);

         extract_element returns NULL if element does not exist
	 
         getenv returns NULL if environment variable does not exist
	 
	 Creation of arrays is now much easier, e.g,
	   i = Integer_Array [10, 20];
	 creates an integer array with 10 rows and 20 columns.  In
	 fact, create_array is nolonger supported by the language;
	 however, it is available as a function in jed/lib/compat.sl.
	 
	 Switch statement syntax modified slightly.  An object is nolonger
	 pushed onto the stack.  Before some code looked like:
	 
	    switch (x)
	      { case '1' or (case (x, '2') : do_this (); }
	      { pop (); do_that (); } % default

         Now it is cleaner:

	    switch (x)
	      { case '1' or case '2' : do_this (); }
	      { do_that (); } % default
	 

   1.  Rmail changes that take Content-Length into account on Solaris
       systems.  Patches for this were submitted by Jan Hlavacek
       <lahvak@math.ohio-state.edu>.
   2.  Another symbolic link bug fixed.
   3.  Stack overflow while doing undo fixed.
   4.  Fixed a small problem when multiple subprocesses exist.
   5.  New wordstar mode by guido@ibogfs.df.unibo.it.  See also ide.sl
       for a borland ide mode.
   6.  Tweaks to make jed work better with gpm 1.13.
   7.  New hook: save_buffer_hook.  See doc/hooks.txt.

Changes since 0.98-3 {{{ 
   0.  Oops.  The pushmode stuff introduced in 0.98-3 also introduced
       a bug.  0.98-3 was pulled for this reason.

}}}

Changes since 0.98-2 {{{ 
   1.  Bug in expand_filename found and corrected.  Tiny bug dealing
       with links also fixed.
   2.  Mark's changes to wmark.sl integrated.  Chaining of

       bufed routines.
   3.  f90 mode updated by joukj@crys.chem.uva.nl.
   4.  Man pages for rgrep and jed provided by borik@isracom.co.il.
   5.  some routine code cleanup
   6.  Tweaks to various modes, edt, c-mode, etc...
   7.  New pushmode.sl file implements push_mode and pop_mode
       functions that facilitate temporary changing of modes in a buffer.
       This requires buffer-local-variable support.
   8.  New global variable Default_Jedrc_Startup_File that may be set
       in defaults.sl to define default jed.rc file.

}}}

Changes since 0.98beta {{{ 
  -2. JED386.EXE now requires a DPMI server.  Read INSTALL.pc for more
      information.
  -1. Ctrl-H now deletes backward.  Experienced users may want to add
        setkey ("help_prefix", "^H");
      in their .jedrc file to restore the old behavior.  The
      help_prefix function is now bound to `ESC ?'.
   0. Patches for VMS and OS/2 applied.  Also features.h changed to
      jed-feat.h to avoid confusion with system header file.
   1. New fold function: c_fold_buffer
   2. Ctrl-X 8 now runs the digraph command for inputting accented
      characters.
   3. Some modifications to sendmail.sl and rmail.sl to make them work
      smoothly together.
   4. If the buffer local variables feature is available, the goto
      bookmark functions will work properly across folds.  A new
      intrinsic function `is_user_mark_in_narrow' was necessary to
      make this possible.
   5. The current buffer position is remembered immediately before a
      call to the goto bookmark function.  To return to this position,
      press the spacebar at the goto bookmark prompt.
   6. Jed has better command line support for info topics, e.g., 
   
           jed -info gcc
	   
      will run jed as an info reader and visit the gcc info page.  In
      addition, an additional parameter may be supplied to specific
      which node to visit, e.g.,
      
           jed -info gcc bugs
	   
   7. rmail_edit function added to rmail mode.  The default binding is
      to the "e" key.  Also simple MIME decoding has been added to the
      rmail mode.

   8. If a command line argument begins with `--', jed will attempt to
      match the remaining part of the argument to a function and
      execute the function.  It will also replace all `-' characters
      by `_' before doing so.  For example, I have a function called
      `no_fold' that sets Fold_Mode_Ok to 0.  I can call this function
      from the command line as `jed --no-fold'  That is, 
      `jed -f BLA_BLA_BLA' is now equivalent to `jed --BLA-BLA-BLA'.

   9. On pc versions, shift arrow keys now generate a distinct
      key sequence from unshifted keys.  See doc/pc-keys.txt for more
      information.
      
  10. New wmark.sl file that implements DOS/Windows style cut/paste
      via shift arrow keys.  Add 
      
           () = evalfile ("umark");
	   
      to your jed.rc file to get this.  Note: it only works on
      terminals that generate distinct escape sequences for the shift
      arrow keys.  This includes the pc versions of jed, Xjed, and jed
      running in rxvt compiled with support for this feature.
      [Luchesar Ionkov is responsible for this feature].
      
  11. joukj@alpha.chem.uva.nl created fortran 90 modes.  See
      jed/lib/f90.sl and jed/lib/ff90.sl.  Also a python mode is
      available courtesy of Harri Pasanen <pa@tekla.fi>.
      
  12. New variable USE_TABS controls whether or not TAB characters
      should be used for whitespace.

  13. New Xjed specific intrinisic function: x_server_vendor
      This function returns the name of X server vendor.  This might
      be useful for setting keysyms on a server by server basis.
      
  14. If GPM Mouse support is compiled in, the new intrinsic function
      `gpm_disable_mouse' may be used to disable the mouse.

}}}

Changes since 0.97-14 {{{ 
   0. Many small architectural changes.
   
   1. Thanks to Andy Harper (A.HARPER@kcl.ac.uk) for work on DCL make files
      for VMS.

   2. Under Unix, ~ is stripped off filename extension before determining
      the mode.
      
   3. rgrep change: -B option may be used to skip binary files.  These files
      are defined to be any file with a null character in the first 32 bytes
      of the file.
      
   4. Folding mode and selective display if jed is compiled with line
      attribute support.  This adds about 4 bytes of overhead per buffer
      line.  As a result, I do not recommend it for systems with no virtual
      memory (DOS).  The 32 bit DOS executable (jed386.exe) does come
      with folding support.  wjed.exe and jed.exe do not provide
      folding support because they are 16 bit executables.
      
      To enable folding mode, you must set the variable Fold_Mode_Ok
      to  non-zero value in your jedrc file.  See doc/fold.txt for
      more information.
      
      `set_color ("...", "blue", "white");' may be used to set the
      color of the "..." hidden line indicator.

   5. Line marks added.  See online documentation `create_line_mark'.
      This is a user mark that has a color associated with it.  A line
      that has a line mark will be displayed using this color.

   6. A buffer-local facility has been added.  See documentation on
      the new intrinsic functions:
      
          create_blocal_var
	  get_blocal_var
	  set_blocal_var
	  define_blocal_var
      
      for more information.
      
   7. If asynchronous subprocess support is enabled, jed will compile
      in the background.
      
   8. Mouse interface completely re-written to be more functional.
      New intrinsics include:
      
          mouse_set_default_hook
	  mouse_set_current_window
	  mouse_map_buttons
	  
      Double and Triple clicking is now supported in XJed.
      
   9. Several new intrinsics including:
   
          usleep
	  is_visible_mark

  10. More sophisticated syntax highlighting added by Simon Tatham
      <anakin@pobox.com>.  His approach based on regular
      expressions is available if jed is compiled with
      JED_HAS_DFA_SYNTAX defined (see src/features.h).  See
      jed/doc/dfa.txt for more information.
      
  11. slang_mode mode line changed from "SL" to "SLang".  This makes
      it more consistent with other modes.

  12. Mark Olesen's sendmail and mail-alias slang packages have been
      integrated into jed.  The sendmail interface replaces the old
      interface on Unix systems.  See sendmail.sl for more information.

  13. I have tried to unify the various makefiles for pc systems.
      There are simply too many compilers and too many incompatable
      make programs for DOS/WINDOWS/OS2 systems and about every other week I
      would receive a new makefile from someone that works with X
      version of make using compiler version Y.  The problem with this is that
      I simply cannot maintain that many makefiles.  See
      jed/src/mkfiles/README for my proposed solution.

Changes since 0.97-13 {{{ 
   0. Some intrinsic functions have been renamed:
        whatmode --> what_mode
        setmode --> set_mode

   1. New functions:
       
        verror, vmessage  : These take a variable number of arguments in
	  vinsert              Sprintf style
	_stk_roll         : rolls the stack
	strchop, strchopr : Chops up a string into substrings

	del_through_eol   : delete through end of line
	pop_mark_0        : equiv to pop_mark(0)
	pop_mark_1        : equiv to pop_mark(1)
	go_left_1         : equiv to go_left(1)
	go_right_1        : equiv to go_right (1)

	bol_bsearch_char  :
	bol_fsearch_char  :
	
      For details, see the online documentation.

   2. narrow_to_region, widen_region:  These are similar to the functions
      `narrow' and `widen' except that these actually delimit editing to a
      region.
      
   3. undo now has redo.  See doc/undo.txt.  This is due to Dan Nelsen
      <dhn@qedinc.com>.
   
   4. In C and SLang modes, the TAB key also adjusts the indentation of
      preprocessor directives.  The variable C_Preprocess_Indent controls
      the amount of indentation.  By default, it is 1.

   5. XJed specific: the resource names have been changed to conform more
      closely with other programs.  In particular, XJed must be changed to
      xjed in your .Xdefaults file because XJed now uses the XTerm class.

   6. Emacs-like insert/copy-to register operations added.  The actual
      functions are called `reg_insert_register' (Ctrl-X G) and
      `reg_copy_to_register' (Ctrl-X X).  These functions are not available
      on 16 bit systems.

   7. Experimental java mode. (Marko Teittinen <marko@tekamah.com>)

      length.

   2. Maximum keyword length for syntax highlighting has been raised from 16
      characters to 20 characters.

   1. Xjed was rejecting command line arguments-- now fixed.

      Ionkov.

         Note: Under MSWINDOWS, os.sl loads a different file (mswmouse.sl)
	 to define mouse actions more suitable to a 2 button mouse.  I
	 suspect that this file should be modified to make the mouse behave
	 more like other Windows programs. e.g., drag mouse to define a
	 region then click a menu item to act on the region.  Any
	 volunteers?

Changes since 0.97-10 {{{ 

   0. MS-Windows version of jed now available.  This is called `wjed.exe'.
      Right now, it is rather primative with no support for menus or shell
      interaction.  Of course the mouse works with the middle button
      simulated by the alt key (see jed/doc/mouse.txt).  Thanks to
      lionkov@sf.cit.bg (Luchesar Ionkov)) for the patches.  (He also sent
      me patches for shell interaction but they would not compile under BCC
      3.1).

   1. There were many complaints about change number 4 in 0.97-6:

           4. XJed: Now when the meta (alt) key is used in
	   conjunction with a non-alphanumeric key such as `{',
	   the character is simply returned. If this creates a
	   backward compatibility problem or appears too
	   restrictive, please let me know.

      Apparantly, this is too restrictive so I have removed the restriction.
      Email me for for a simple way around this lifting of the restriction.
   2. Directories with names ending in ~ were not getting expanded properly.
   3. Slang Version 0.99-19 is now required.  This implements the new
      intrinsic function `strcompress'.
   4. QNX support added.
   5. Support for an alternate set of keywords added.  The C-mode defines some
      of these keywords such as `exit', `malloc', `strlen', etc...  Use
      something like:
      
          set_color ("keyword1", "green", "white");
	  
      to set the colors for this set.
   6. A couple of MSDOS jed bugs found.  One affects the keyboard and the
      other fix corrects a bad regular expression when compiling using bcc.
    
   7. idl mode enhanced with indentation.

   2. New functions: _autoload and _add_completion.  See function
      documentation.  Briefly, these permit slightly faster loading.
   3. Typos corrected in shell.sl, emacs.sl, and dired.sl.
   4. Small correction for file name expansion under VMS.
   5. Ran purify on source code and fixed about two bad memory references.

Changes since 0.97-7 {{{ 
   1. The F1-F12 keys may now be used with jed386.exe and edt.sl.  See
      jed/doc/jed_faq.txt for more on EDT mode and jed386.exe.
   2. The `untab' function has been fixed.  I broke it in 0.97-7 (see below).
   3. Somewhat nasty bug fixed that affected jed386.exe.
   4. Unix and VMS: If the environment variable `COLORTERM' is defined, jed
      will automatically set the variable USE_ANSI_COLORS to a non-zero value.
      This feature is only available when compiled against slang version
      0.99-14.  Patches have also been sent in to the maintainer of the
      color xterm `rxvt' to automatically set this variable.  Incidently, if
      you are using `color_xterm', I suggest that you try out `rxvt'.

Changes since 0.97-6 {{{ 
  -1. Mouse support added to OS/2 version.  (Thanks to John Burnell.   
      <johnb@whio.grace.cri.nz>)

   0. ``Expansion hook'' added.  This hook is called upon TAB completion to
      preprocess the file before completion.  The default definition of this
      function expands environment variables when the variable is preceeded
      by a dollar sign, e.g., $HOME.  This function has not been defined for
      VMS since VMS already has this feature built in.

      Under Unix, this function also expands ~name to the login directory of
      the user `name'.  The expansion only takes place when the TAB key is
      pressed.
      
      The new intrinsic: set_expansion_hook may be used to change the hook.
      
   1. Under Unix, the function `get_passwd_info' may be used to return
      information about a specified user such as login dir, shell, etc...
      
   2. TeX mode highlighting fixes:
        a. words containing accents now handled properly
	b. The TeX special characters `&_^#' are now colored as `operators'.
	c. Braces `{}' are colored as delimiters.

   3. A prefix argument to the `untab' function will cause spaces to be
      converted into tabs.
      
   4. Page up/down commands modified slightly to give appear more intuitive.
   
   5. Misc bug fixes including:
       a. Parenthesis matching now works when `(` is also a comment delimiter.
       
   6. Pasting using the mouse has changed slightly.  Previously, text would
      be pasted at the position of the mouse.  Now, it is pasted at the
      position of the cursor.  This seems more intuitive.
      
      In addition, the editing position is restored to what it was before
      dragging text into the cutbuffer.  Again, this is more intuitive and
      more closely follows the Xterm usage.
      
   7. In C-mode, a if a line is preceeded by a line that ends with \, it is
      indented to the first column.  This is useful for continuation lines.
   8. Better native support for SunOS keyboards (pageup/down/home/end).
   9. The function `shell_cmd' has been changed to return the exit code of the
      subprocess.  Previously, it returned nothing.
  10. idl mode added.  Actually, only syntax highlighting is defined.  This 
      mode takes effect on .pro files.

}}}

Changes since 0.97-5 {{{ 
   0. New routines for adding keywords.  These include:
   
        add_keyword, define_keywords
	
      See shmode.sl for an example.  Basically, this file implements syntax
      highlighting for Unix sh and csh files.
      
   1. Bug fixed in filename completion.
   2. Kevin Humphreys auctex-for-jed package has been integrated into the
      source.  Thanks Kevin.
   3. Popular combinations of slang functions have been combined to create
      new functions.  These include:
   
         bol (); skip_white ();    ------------------> bol_skip_white ();
	 down (1);                 ------------------> down_1 ();
	 go_down (1);              ------------------> go_down_1 ();
	 up (1);                   ------------------> up_1 ();
	 go_up (1);                ------------------> go_up_1 ();
	 
      These load twice as fast and use half as much memory.  If I make them
      into intrinsics, they will execute twice as fast.  Jed slang
      programmers are encouraged to use these.
      
   4. XJed: Now when the meta (alt) key is used in conjunction with a
      non-alphanumeric key such as `{', the character is simply returned.
      If this creates a backward compatibility problem or appears too
      restrictive, please let me know.
      
   5. XJed: XJed now will never read a file from stdin.  This means that the
      *stdin* buffer will nolonger appear when it is started from a menu by
      the window manager.

Changes since 0.97-4a {{{ 

   0. A COMPLETE rewrite of all the indentation routines.  The new routines 
      are much more customizable through the use of syntax tables.  Now, the
      C mode is completely written in S-Lang.  
      
         New features: 
	 
	    * Now much easier to add support for new languages.
	    * ESC-q will format a comment if it is in the canonical form:
	       /*
	        *  This is a C comment in
		*  the canonical form
		*  Notice how each line
		*  begins with a `*'.
		*/
	    * `goto_match' now works in both directions.
	    * New C-mode functions: 
	        c_end_of_function : ESC Ctrl-E
	        c_top_of_function : ESC Ctrl-A
	        c_mark_function :   ESC Ctrl-H
      

   1. The function `whatline' has been renamed to `what_line' for consistency 
      with other names.
      
   2. New function: translate_region.  This function is capable of modifying 
      all characters in a region according to a lookup table.  This is useful
      for converting buffers between various character sets.  See the new
      version of jed/lib/rot13.sl for an example of its usage.
      
   3. New functionality: yank-pop.  This is implemented in jed/lib/yankpop.sl.
      Unfortunately this is not available on 16bit systems.  This means if you
      use jed.exe you cannot use it.  However, jed386.exe is a 32bit
      executable so it is available.
      
      If you do not know what yank-pop is already, do not worry too much.
      You should not notice its presence.  However, if you do, hopefully you
      will welcome jed's emulation of it.  This was added to improve the
      emacs emulation.  See jed/doc/yankpop.txt for a simple discussion.

   4. New intrinsic variable _jed_version added.  This variable is an integer
      that represents the version number.  For 0.97-5, it has the value 9705.
      For 0.97-11, it will have the value 9711 and so on.
      
   5. A bug in jed386.exe was corrected.  This bug was responsible for
      some keyboard lockups.
      
}}}

Changes since 0.97-4 {{{ 
   1. Intrinsic function documentation improved.
   2. Source code should now compiled without specifying VAX compatability
      on ALPHA/AXP systems running OpenVMS.  Use the deccmake.com files to
      create jed & slang.


}}}

Changes since 0.97-3 {{{ 
   1.  New intrinsic functions:
         set_color_object: Associate a foreground/background color pair with
	    an integer, e.g., set_color_object (31, "green", "red");
	 set_column_colors: Allows one to display the columns of a buffer in
	    different colors.  For example:
	    
	       set_color_object (31, "green", "white");
	       set_color_object (32, "red", "white");
	       set_column_colors (31, 1, 40);
	       set_column_colors (32, 41, 80);
	    
	    Display columns 1 to 40 in green/white and columns 41 to 80 in
	    red on white.  This operates on a buffer by buffer basis does
	    not work when there is syntax highlighting already associated
	    with the buffer.
	    
	    This function is only useful when the buffer consists of data
	    organized in columns, e.g., columns of numbers, dired mode,
	    rmail mode, etc...
	    
	 str_replace: replace substrings in strings

   2.  In XJed, set_color("normal", "foreground-color", "background-color"),
       now works.  This means it is nolonger necessary to mess with
       .Xdefaults to set the background color. 

   3.  Small problem with expansion of symbolic links fixed.
   4.  It is now possible to set the color used for messages and errors.
       This is accomplished by using, e.g.,
       
            set_color ("message", "blue", "white");
            set_color ("error", "red", "white");

   5.  A problem with info failing under VMS has been fixed.

   2.  Mouse support under MSDOS.  Read doc/mouse.txt for information.
   
   3.  Fixed a keymap problem in Xjed (specifically for Ctrl-_ and Function
       keys).

   4.  Problem with replace_across_buffer_files corrected.
   5.  If a file is edited for which one does not have write permission,
       the buffer is made read-only.

Changes since 0.96-2: {{{ 

  -20. A bug introduced by `-18' beow that prevented searches from working
       properly when using a macro has been fixed.
       
  -19. `dired' modified such that ^K nolonger runs the function
       `dired_kill_line'.  Instead, one must do:
       
           define dired_hook ()
	   {
	     local_unsetkey ("^K");
	     local_setkey ("dired_kill_line", "^K");
	   }
	 
	See jed.rc where this is performed.

  -18. RETURN key may be used to continue searches.  Also, matches are
       highlighted.  

  -17. Variable `No_Backups' added to control whether or not JED is to
       create backup files.
       
  -16. Command line argument parsing modified (in site.sl) to make it easier 
       to write non-interactive scripts, e.g.,
       
          jed -script my-script.sl file1 file2 ...
	  
       Basically, `-script' simply loads the next argument (my_script.sl).
       It is up to the script file to interpret the remaining arguments.
       See doc/script.txt for more info.

  -15. Trivial modification that allow JED to become a GNU-info reader 
       by using: 
  
         `alias info jed -f info_reader'    (Unix csh)
	 $ info :== jed -f info_reader      (VMS)

  -14. A VMS bug fixed.  Specifically, the getkey AST is now disabled while
       the main thread is accessing the keyboard buffer.

  -13. NEW abbrev mode.  This is a major rewrite of the old abbrev mode.  See
       jed/doc/abbrev.txt for details.

  -12. `read_string_with_completion' added to read a string in the mini buffer
       using a list of strings for completion.

  -11. Major change in S-Lang library removes the need for functions such as
       `free_array'.  As a result, this function has been removed.
       
  -10. abbrev mode.  This differs from `dabbrev' in the sense that you can
       define global and local abbreviations and use them.  The function
       `toggle_abbrev' may be used to turn the mode on/off.  See abbrev.sl
       for details.
       
   -9. mousex.sl package adds mouse routines to any terminal using the XTerm
       client mouse protocol.  Such terminals include the Linux console
       running selection as well as XTerm itself.  Note: this could be made
       available across a dialup line from a PC using MS-Kermit, Procomm,
       etc... if someone would write the appropriate mouse TSR.

   -8. Added `tex_ldots' binding that converts three `.' to \ldots.  
   
   -7. `replace_across_buffer_files' added.  This function allows the user
        to replace a string across all buffers attached to a file.  It is 
	interactive.
       
   -6. Book marks added: `bkmrk_goto_mark' and `bkmrk_set_mark'
       These functions allow the user to set up to 10 bookmarks (0-9)
       and return to a previously set book mark from any buffer.
       These marks are implemented using new jed intrinsics:
       
          `user_mark_buffer'  : returns buffer name associtated with mark 
	  `goto_user_mark'    : goto position specified by mark
	  `create_user_mark'  : returns a mark at the current position
	  
   -5. Automatic detection of ``non-native'' line endings.  On Unix, if a 
       file is read in with ^Ms at the end of lines, it is flagged such that
       writing out the file will preserve the line ending attributes.  A `C' 
       will appear on the status line to indicate this fact.  On DOS, etc...
       if a file is read in without the ^M, it is flagged and an `L' will
       appear on the status line.  Use the function `toggle_crmode'
       to change the attribute.
       
   -4A. New ways added to facilitate associating modes with files:
   
         a.  add_mode_for_extension ("c", "c++");
	     This asscoiates c_mode with a file named something.c++.
	 b.  If top line of file contains something like: -*- mode -*-
	
       Note that in both cases the mode argument must omit the `_mode' part
       of the name.  In fact, all modes now have names that end in `_mode'.
       
   -4B. `fortran' and `dcl' have been renamed `fortran_mode' and `dcl_mode'.

   -3. C mode indenting improved.
   -2. Writing to terminal under VMS SIGNIFICANTLY improved.  Basically I
	just bypassed the VAXC buffered stdio routines in favor of my own.
	This might improve performance for Unix systems as well.
   -1. Emacs style completion added-- press tab to show completions, press
        space to cycle through them.  Note that pressing PageUp/Down keys
	will scroll the completion buffer from the minibuffer.
    0. Bug fixes
    1. Massive restructuring.  Keymaps, Searching, and Terminal I/O moved to
	S-Lang. 
    2. color syntax highlighting in FORTRAN, TeX, and C modes.
    3. TeX mode enhanced--- more to come.
    4. ``menu'' bar can now be hidden-- see jed.rc.
    5. More hooks: c_mode_hook, tex_mode_hook, text_mode_hook, wrap_hook
    6. Better documentation on hooks (see doc/hooks.txt).
    7. showkey binding changed to `Ctrl-H k'.  Also rectangle commands are
       now bound in emacs.sl to emacs bindings.
    8. Mute (Dead or accent) key support added.  See jed.rc
    9. gzipped info file support added for MSDOS
   10. Alt key processing for X-Windows fixed.
   11. Significant additions to dired, e.g, `~' flags all backup files.
   12. Visible bell add to systems that support it (Xjed, pc and OS/2,
       Linux, etc...).

    5. If JED is started without a filename specified, the brief message will
       be displayed warning the user that the scratch buffer will not be
       saved.
    6. On MSDOS, rgrep.exe (recursive grep) is now distributed.  ON Unix,

    1. re_fsearch and re_bsearch functions have been changed to return
       1 + the length of the match, if a match was found, or return 0 if no
       match was found.  For example, `re_fsearch("$")' matches the end of a
       line which, strictly speaking, is a match with 0 length.
       
    2. Use `jed -l preparse' to pre-parse the .sl files for faster loading.
       `jed -l preprocess' is now obsolete.  Again, read install.*.

}}}

Changes since 0.95-7b: {{{ 

    1. Color syntax highlighting added to C mode.  It is possible to
       separately color keywords, strings, numbers, delimeters, comments,
       and operators.  This even works on VMS and Unix systems when using
       character based color terminals such as NCSA telnet, MS-Kermit, 
       etc...  See doc/color.txt and doc/syntax.txt for more information.
       
    2. byte compiling changed to allow preprocessing only.  Simply
       preprocessing is recommended on systems where more than one type of
       JED executable will share the same set of *.slc library files (e.g.,
       Unix where both JED and XJed might be running).  Simply do:
       
          jed -batch -l preprocess.sl
	  
       On MSDOS systems with only one version of jed.exe running, use:
       
          jed -batch -l bytecomp.sl

Changes since 0.95-6b: {{{ 

    1. It is now possible to display 24 hour time on the status line.
       Earlier versions were capable of displaying on AM/PM format.

    2. -tmp command line switch added.  This means that the current buffer
       is to not be autosaved or backed up.  This is suitable when JED is
       used as an editor for elm, etc...

    3. DJGPP version fixed so that JED can read embedded ^M characters and
       ^Z characters while in text mode.  Of course the ^M is striped if it
       preceeds a line feed character.
       
    4. Improved fortran mode.  The fortran mode is the first mode that I ever
       wrote for JED using S-Lang.  Since then, I have had alot of experience
       with S-Lang and recently I found myself programming FORTRAN again, so
       I rewrote it.  Do `Ctrl-H f fortran' for details.

    0. XJED now compiles as a DECWindows executable under VMS.
    
    1. The interactive replace function has been renamed to `replace_cmd' and
       is now implemented in S-lang. It can now search/replace across lines.
       For most users, this change should be transparent.
       
    2. New functions: 
    
          set_buffer_no_backup ()
          set_buffer_no_autosave ()
    
    3. XJed mouse changes:

          Clicking on a window status line causes a different behavior.
	  Specifically:

                left:  switch to next buffer   
		middle:  split the window
		right:  delete the window

          For example, one can quickly move from one buffer to the next by
	  simply clicking on the status line with the left mouse button.

    4. XJed can nor distinguish shifted and control function keys.  This
       enables one to bind Shift arrow keys and Control arrow keys to
       different functions.
     
    5. Improved indenting in C-mode.

	 new buffer for that window.  This makes it possible to conveniently
	 cycle through all buffers.
	 
    6. rgrep flag now added so that directory links may be followed.  Rgrep
         is a recursive, highlightin grep that is distributed with JED.  See
	 doc/rgrep.doc for more information.

    7. The search forward/backwad commands are now S-Lang functions which
	 means that they may be changed easily.
	 
    8. New function for PC versions (DJGPP too!): find_binary_file.
         This function will prompt for a filename and find it in binary
	 mode.  A binary mode file is indicated by a `Z' status line flag.
	 This means that when the file is saved, it will be saved in binary
	 mode as well.  This function provides a transparent way to edit
	 binary files under DOS.
	 
    9. JED now understands 8 bit control sequences generated by terminals in
         8 bit mode such as DEC VTXXX.  This is particularly relevant when
	 using JED on VMS.

Changes for version 0.95 (since 0.94-2)

    0. JED distribution is different.  If you have built JED in the past,
       please read the install files because things have changed.
    1. Support for column numbers on status line (set LINENUMBERS = 2)
    2. X-Terminal (and DECWindows) version (make xjed).  See doc/xjed.doc
    3. Elm like read/write mail (see rmail.txt-- this is considered ALPHA,
        by default it is not enabled.)
    4. Additional support for Color terminals (allow different colors for
        modelines, regions, etc...)
    5. MUCH Improved support for colors on PC versions (looks MUCH nicer,
         see how it is used in jed.rc)
    6. By popular demand, a new function `describe_bindings'  is available
         that dumps the keybindings for the current keymap.
    7. New variable Stratup_With_File can be set to prompt user for
         a filename if none is specified on the command line.
    8. VMS: A convenient new interface to VMSHELP is now available.  This
         overcomes most of the shortcomings of the VMS HELP command.  
	 It is bound to Ctrl-H M.
    9. search_forward + search_backward can now search for strings spanning
         multiple lines.  Also, looking_at can see across multiple lines.

Also see changes listed in the next section.

*********  Important **************

The S-Lang preprocessing conditional compilation declarations have changed.
Now, constructs such as:

#ifdef UNIX
  ..
#else
  ..
#endif

are used.  This means  that you may have to edit you personal jed.rc file.
Instead, I encourage you to simply copy the jed.rc file shipped with this
version and add your own extensions to it.

New changes SINCE 0.94-0: {{{ 

    1. New buffer flags:  no backup and no autosave
    2. #ifdef #else #endif preprocessing
    3. skip_chars, bskip_chars changed.  Now, say, `skip_chars("^a-z")' will
         skip ALL characters EXCEPT in range `a-z'.
    4. Default EDT binding of TAB changed to `indent_line'.  See jed.rc
         to change it back.
    5. `occur' function now uses regular expression searches.
    6. Special `linux.sl' file for Linux systems.  See `install.unx'.
    7. New intrinsics: buffer_visible, pop2buf_whatbuf, bury_buffer,
                       regexp_nth_match,
    8. `window_info' intrinsic modified to take a parameter.
    9. `search_file' intrinsic modified for regular expression search.
   10. New support for saving and reusing keyboard macros.  This feature
       has not been exploited yet!
   11. By popluar request:  Highlighting only occurs in the CURRENT window.
   12. Miscellaneous bug fixes.
   
There are also some new S-Lang builtin intrinsic functions:

    1. string_match: preforms RE match on a string
    2. string_match_nth: returns information about previous match
    3. Unix specific intrinsics:
    
          unix_kill  :  sends a signal to a process
	  unix_ctime :  converts a time value to a string representation
	  stat_file  :  performs `stat' on a given file.
	  lstat_file :  like stat but returns information about a link
	  stat_struct:  returns information from previous stat call.
	  chown      :  change owner/group of a file
	  chmod      :  change protections of file.
	  
    4. It is now possible to perform assignments in variable declaration
       statements:
       
          variable i = 10, y = 20.87;
	  
    5. && and || are now flagged as errors.
    
******************************    
New since 0.94-0 : ------------------------------------------------------------

PageUP/Down functions scroll other window if called from the minibuffer.

Some defaults changed in jed.rc:  Display line numbers on the status line
  is now the default.

Regular expression matching (search/replace):
     re_search_forward, re_search_backward, query_replace_match
    
New S-Lang intrinsics include:

     prefix_argument()  : returns value of prefix argument.
     set_status_line(format, flag) : enables user to customize status line
     re_fsearch, re_bsearch, replace_match  : regular expression intrinsics
     getpid  : returns process pid

New user variables:

DISPLAY_TIME  if non-zero, allows %t processing in status line format.
ALT_CHAR   (ibmpc only) enables Alt-key processing.  Specifically, setting
           this to 27 (Ascii 27) causes ALT-X to generate ESCAPE-X, etc...
	   
C_BRA_NEWLINE if non-zero, insert a newline before inserting '{' in C-mode.
           This was the default in previous versions but it now user
	   selectable.

------------------------------------------------------------------------------
New features in 0.94-0

0.94-0 does not really add any new functionality to 0.93.  However, there is a
major change:  S-Lang is now very C-Like.  (It can still be programmed as
RPN though, see e.g., info.sl)  By C-like, I mean that you can write S-Lang
functions that look like:

    define sum(a, b)    % sum integers from a to b
    {
      variable s, i;
      
      s = 0;
      for (i = a; i <= b; i++) s += i;
      return (s);
    }
    
S-Lang has not lost any functionality, rather, its new syntax makes it more
accessable to others.

The new philosophy is that JED is an editor which just happens to embed
S-Lang as its extension language.  Actually, this has always been the
philosophy but not it is even more clear cut.  To compile the new JED (0.94)
you will need to pick up /pub/slang/slang.tar.Z as well.  This is the S-Lang
interpreter code to be compiled as a library and linked in with JED.

The only other ``major'' changes are:

  1. do_while construct added:
  
     do { stuff... } while (expression);
     
  2. `defined?' replaced by `is_defined'.
  3. Temporary global variables $0, $1, ... $9 added for convenience and
     clarity.
  4. Comment delimeter changed from `;' to `%'.
  5. Arrays are indexed from 0 not 1.
  6. \??? is now Octal ??? NOT decimal ???.  \d??? is decimal.
  7. Sprintf added to intrinsics (formats strings)
     
In addition, you should ``bytecompile'' the .sl files after installing the
new version of jed.  It is this simple:

    jed -batch -l bytecomp.sl
