VMS_SHARE  6.10					7-FEB-1989


6.10 - UPDATES SINCE 6.08
-------------------------

New Features:
   - Allow a new logical name to be defined: SHARE_DISPLAY. This is a subset
     of the function of SHARE_VERIFY in that it turns on tracing but only
     for messages generated by TPU. messages are sent to SYS$OUTPUT. It
     does NOT echo lines of DCL code or TPU code used within VMS_SHARE.
     Its primary function is debugging VMS_SHARE itself.


Bug Fixes:
   - VMS_SHARE now works with VMS5. Due to changes in the way TPU dealt
     with pattern searching, VMS_SHARE looped indefinately trying to
     find a split point in a long line.

   - A spurious blank line was inserted into the DCL control commands of
     VMS_SHARE. Under VMS4 this was ignored. Under VMS5, lines not starting
     with $ are rejected.  This blank line no longer appears.


Modifications:
   - Made use of an error handler in the QUOTE_BUFFER procedure to
     avoid an unwanted error message when SEARCH does not match at
     the end of the buffer. When VMS 5 is more widespread, this will
     be altered to use the SEARCH_QUIETLY procedure.

   - Modifed the names of several local variables to avoid conflicts
     with global variables pointed out by the VMS 5 TPU compiler. They
     were not wrong originally but they've been fixed to 'clean' up the
     code.

   - VMS_SHARE now used a combination of STR and LENGTH functions to
     determine the number of digits in a number. Previously this was a long 
     chain of nested IFs.



6.08 - UPDATES SINCE 6.06A
--------------------------

New features:
   - PAKMAIL enhanced to accept an extra parameter (P4) to allow inclusion
     of a comment in the MAIL /subject header.

Modifications:
   - PAKMAIL now returns the correct exit status code to allow for error
     checking following return from the procedure.



6.07 - UPDATES SINCE 6.06A
--------------------------

Modifications:
   - Code to deal with file input rewrittem so that
        o One file at a time read and processed
        o Less buffer space used overall
        o Commoned up two similar sets of code



6.06A - UPDATES SINCE 6.06
-------------------------

Modifications:
   - Changed max line length to 77 as some mailers object to longer lines


6.06 - UPDATES SINCE 6.03
-------------------------

New features:
   - Allows definition of logical names to define some options:
       o max part size
       o verification (for code debugging only)
       o real name definition (previously a symbol was used)
   - Includes a new procedure (PAKMAIL) which allows easy distribution
     of the various parts of a VMS_SHARE'd package to the network via
     E-Mail.
   - Help file for both VMS_SHARE and PAKMAIL


Bug Fixes:
   - Added missing parameter to FAO to get correct date in file header.
   - Loop constructing ASCII codes was off-by-1.  '255' now escaped properly.
   - Shortened a DCL LINE in the preamble which was longer than 80 chars.
   - Fixed some stuff relating to infinite loops when dealing with blanks.

Miscellaneous Mods:
   - Improved packing algorithm to get the initial TPU code in.
   - Simplified code via procedures
   - Various minor speedups of the packing stuff.
   - More comments added!


I'll be happy to try to incorporate further mods if details are sent to me. 
particularly in the area of speeding up the various pack/unpack algorithms 
used - I find these horrendously slow when processing large'ish packages!
