                 Richmond, VA.

         Operating system:  RSX-11M+ V3.0 forward.  Other RSX  systems
                 with reduced functionality.

         Language:  FORTRAN-77, MACRO-11

         Memory Required:  32KW

         Other Hardware Required:  None

         Keywords:  Utilities - RSX11

         Abstract:

         LBC  provides  a  non-structured  disk  copy   facility   for
         direct-access  media  under  RSX.   All  or  part  of  a disk
         (mounted foreign) or a file may be copied to another disk  or
         file,  or  to  another location on the same disk or file.  In
         the case of file-to-file operations, the  attributes  of  the
         input  file  can  be  preserved.  Because up to 64 blocks are
         moved at a time, performance is reasonable.   Error  recovery
         is done by reducing the number of blocks per QIO and retrying
         the operation; if a single-block  QIO  fails,  the  error  is
         logged and a block is skipped on both input and output.

         LBC can be invoked in any of the standard  ways  for  an  RSX
         utility.   The  command  interface  is DCL-like, and includes
         prompts for missing information.

         Full default file name support  as  documented  requires  the
         PRMS$  directive  (ie  - RSX-11M+ V3.0 or greater).  Older M+
         systems, or M systems, require more typing  but  should  work
         otherwise.

         This release includes  two  minor  bug  fixes:   the  highest
         logical block number for a disk was calculated incorrectly in
         the previous release (88.126), and the  call  to  PRSRMS  was
         bypassed for 11M.  Otherwise, the two are identical.
