NARC.EXE REVISION HISTORY
ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ

Version 1.0 - First Release 6.10.87 (Beta Release)

Version 1.1 - Released 6.16.87 (Beta Release)
- Fixed bug in tagged extraction to other than default path
- Deletes partial file when extraction fails due to lack of disk space
- Fixed bug dealing with improper end of file condition in HEX view
- Stronger ARChive header checking. Handles special case where two
1Ah bytes are encountered after a bad header
- Fixed bug with PK zero length files
- Introduction of NARCCFG.EXE, replacing NARCLOAD.EXE and NARC.CFG

Version 1.2 - Released 8.10.87 (First "real" release)
- Fixed bug in ARC window when no ARC files. NARC wants F1,F2 or F3
but bug caused a wrong keypress to send "twirping" sound to spkr.
Program seemed to be locked up, but ALT key would continue.
- added PAGE UP, PAGE DOWN, HOME and END functions (great for big ARCs)
- corrected bug when using some of the single letter commands in
extracting (this was a stupid mistake on my part)
- added FIND command for locating sub-files (great for big ARCs)
- added file deletion
- added abort option to tagged extraction when disk full
- added display of number of tagged files and tagged bytes
- added formatted display of tagged file and tagged bytes
- changed write color in Blank routine
- enhanced extract and print abort
- check disk space BEFORE extraction
- added help facility
- 70% FASTER EXTRACTION !
- added code to check for seek past EOF in when bad ARC file has
enormous numbers for file sizes
- fixed ELUSIVE bug in repeated byte expansion when the count byte
was the REP byte
- added Tag All option (F6 key)
- added invert all tags option (F7 key)
- added sound toggle to NARCCFG.EXE (turns sound on and off)

Version 1.3 - Released 11.24.87
- when sub-directory selected that has no ARC files, now shows
No ARC files window.
- HELP available in No ARC file window
- END key takes you to bottom of ARC subfile directory
- help window shows functions available on sub-dir window
- NEW view function includes Pgup,Pgdn,Home,End,Arrows
- removed check for disk space BEFORE extracting. This was done
since MOST extractions will proceed correctly and when this is
done on all extractions, speed is sacrificed. If a write is
unsuccessful, then the user is aked to continue or abort
- added page UP/DOWN/HOME/END to pop up windows
- added command line syntax options compatible with ARC and PKXARC

D,-D = delete submask file from ARCmask
X,-X,E,-E = extract submask file(s) from ARCmask
P,-P = print submask file from ARCmask
V,-V,L,-L,T,-T,Z,-Z = open ARCmask file and display files
