ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ 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 C,-C = view submask file in ARCmask H = help screen The default archive extension is ARC, but can be overwritten with ARK by the user. Commands may be preceeded by "-" or "/" - added ALT-F10 status screen Version 2.0 - Released 04.19.88 - visual tree routines - context sensitive HELP screens - F9 = call editor function - I = call IDC-ARC.EXE - saves/restores users video mode - new mouse routines - installed critical error handling routine - 60% to 88% faster extractions, due to new mouse routine and slicker decompression algorithm - moved string table into CSEG (speed, no longer need to swap segments when accessing string table) - added ALT-letter find option in menus/lists - disk reset when changing drives - prompt before exit - added text search in view and mouse support - expanded mouse support throughout - BIOS or DIRECT video writes - forced black and white mode - accepts non-standard file extensions (S-command) - fixed random extraction failure - fixed delete file bug (see NARC.NEW) - added ^R repeat key for extraction path Version 2.1 - Released 04.24.88 - bug in 2.0 caused error in files when extracting. If you tagged several files that were not one-after-the-other in the ARC, the second and subsequent files would not have the correct data in them, even though NARC flagged no errors. Highlighted and tag all extractions worked fine. Version 2.2 - Released 04.27.88 - fixed minor bug in color configuration. Wouldn't allow forced B&W mode Version 2.3 - Released 07.28.88 - maintenance release. - fixed problem with extracting files after encountering a damaged archive header - added ctrl-break and ctrl-c interrupt intercepts - improved buffering scheme when extracting - fixed color bug on return from shell when in MONO mode Version 2.4 - Released 08.04.88 - changed hardcoded filename of IDC-ARC to IDCshell Version 2.5 - Released 12.31.88 - went to DOS EXEC function in lieu of Int 2Eh - DOS 4.0 support - added print directory tree function - fixed bug in directory tree routine when exactly 19 subdirectories were present on a disk Version 2.5a - Released 01.20.89 - fixed bug in directory tree under DOS 4.x when partition was larger than 32MB Version 2.5c - Released 02.16.89 - no major changes Version 3.0 - Released 05.08.89 - added ZIP file format support - fixed bug in print directory tree - added permanent pathname installation in NARCCFG instead of the environment variables (registered users only) - fixed print bug - fixed bug in ^R repeat of last string when entering text and then editing the retrieved text. - added 43 line mode support Version 3.0a - Released 05.11.89 - fixed bug in clear screen on some machines Version 3.0b - Released 05.13.89 - another fix with same bug as above Version 3.0c - not released Version 3.0d - 5/31/89 - complete rewrite of command line options - fixed bug in 43 line mode, shell to DOS and return in 25 line mode, but NARCs parameters still in 43 line mode - added sort option to zipfile window - enhanced print abort - fixed delete subfile bug - added SHARE DENY WRITE modes when opening files in DOS 3.x and above Version 3.0f - 07/03/89 - fixed another delete subfile bug. The subfile was actually deleted ok, but NARC gave errors when trying to reopen the file. Exit program and bring it up again, all is ok. Version 3.1 - 10/21/89 - added IMPLODING algorithm support. - added ALT-F3 screen which displays stored pathname Version 4.0 - 4/27/90 - added support for 1.1 zip header - added password decrypion - added NETWORK and modified DOS compatibility (no FAT reading) - fixed bug in exit options when ENTER selected End of file
