FLX -- FILE TRANSFER PROGRAM FLX provides a means of transferring files between various PDP-11 operating systems. The primary media format is DOS. To run FLX, type FLX devicespec/sw=infile/sw,...,infile/sw. Note FLX never allows output file specifications. By default it is assumed that input files are DOS format and output files are RSX format. To change the format use a format switch to specify the file type. /DO DOS format /RS RSX format /RT RT11 format Further HELP keywords are TRANSFER-MODE SWITCHES 2 TRANSFER-MODE FLX can transfer data in Formatted ASCII, Formatted Binary, and Image Mode. Playing with these switches can cause many problems. Read the manual (page 5-4 of the Utilities manual), or assume that the default settings are used. /FA:n Formatted 7-bit ASCII. /FB:n Formatted Binary. /IM:n Image mode. Some file extensions default to certain transfer-modes as follows:- /IM .TSK, .OLB, .MLB, .SYS, .SML, .ULB /FB .OBJ, .STB, .BIN, .LDA /FA All Others This should be borne in mind if transferring files under non- standard extensions (e.g. VMS task images as .EXE). 2 SWITCHES /BL:n Indicates the number of contiguous blocks to allocate to an output file(must be used with the /CO switch). /BS:n Specifies block size on cassette tape output. /CO The output file is to be contiguous. /DE Delete files on DOS-11 DECtape or disk. /DI Provide a directory listing of DOS volumes. /DNS:n Specify density of magnetic tape. /FC Set Fortran carriage control conventions. /ID Display's FLX's version number. /LI Same as /DI. /NU:n Used with /ZE and /RT switches to specify number of directory blocks to allocate on an RT format disk. /-RW Do not rewind magtape before transfer. Must be on same side of commandline as the magtape. /SP Spool the output file. /UI The output file is to have the same UIC as the input file. /VE Verify records written to cassettes. /ZE Initialize RT, or DOS volumes.
