                          NARC version 1.3 enhancements


Speed improvements.

       This version of NARC has a greatly streamlined uncruncher. The
       result is an additional 22% decrease in extraction times. Version
       1.3 uses a very large stack, which avoids a time consuming link
       and relink operation on the string table when decoding each string.


Full EGA support.

       I finally got an EGA card, so NARC followed. (You're welcome Gene!)


Handling of sub directories with no ARC files.

       There were many complaints about how NARC handled this situation.
       Previously, NARC simply would not let you select a sub directory that
       contained no ARC files (there is no reason to go there anyway), but
       this caused a lot of confusion and in response the handling of this
       situation has been revised. NARC will now show the NO-ARC-FILES window
       and give several options.


Expanded HELP

       HELP is now available from the NO-ARC-FILES window.


Expanded movement in the pop up windows.

       The HOME,END,PG UP, PG DN and arrow keys now work in all windows.


New help windows.

       There was also a lot of confusion about the subdirectory window and
       the commands available in that window. There is now a help window
       that pops up along with the sub directory window showing all available
       commands. There is a similar window that pops up along with the
       ARC file window.


New View function.

       This rewrite is the direct result of an overwhelming amount of user
       requests. (I took a beating on this one!)

       The HOME,END,PG UP, PG DN and arrow keys all function in view now.
       There is a WordStar (c) type filter toggle (the "F" key) and a HEX
       dump mode toggle (the "M" key) that are available at all times.
       NARC first extracts the file to the default drive into a file called
       NARC.TMP and then proceeds to view the file. When viewing is finished,
       the NARC.TMP file is deleted. If there is not enough room on the
       default drive to create the NARC.TMP file, you are prompted for
       another drive that can be used for the temporary file. The ESCape
       key will end the view session.


Trivia status screen.

       This is a new screen that shows some semi-useful information about
       the current NARC environment. The screen is invoked from the
       main NARC screen via the ALT-F10 key sequence.


Removed check disk space BEFORE extraction feature.

       This feature was removed after rethinking the process. This was done
       since MOST extractions will proceed correctly and when this is
       done on all extractions, speed is sacrificed. If a disk write is
       unsuccessful, then the user is asked whether or not to continue
       (if extracting tagged) or abort. If the user aborts, then any partial
       file is deleted.


Command line processor.

       A command line processor has been added that is compatible with
       both ARC and PKXARC. There are some variations on the implementation
       of these commands that are not wholly compatible with ARC and PK. For
       example, the ONLY command that operates on wildcard subfiles is the
       extract command. The "T" (test ARC integrity command) will simply open
       the ARC file and display the main NARC screen. This is done, since NARC
       does the integrity check when reading the ARC file. The "D" (delete
       subfile) command will only delete one file at a time. This is done
       since it is very seldom that files are deleted from an ARC anyway and
       the wildcard can be very dangerous.

       Command line syntax:

               NARC  [command] [ARC file] [submask]

       where;

       [command]      may be any of the following and may be preceeded by
                      "-" or "/"

               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                       = shows command line options

       [ARC file]      may be any ARC file with or without the extension. An
                       extension of .ARC is assumed, but may be explicitly
                       inlcuded as .ARC or .ARK. The drive/path may also be
                       included.

       [submask]       may be any valid wildcard filename.

               Registered users of NARC now have the option of communicating
               directly with Infinity Design Concepts via the GTPowercomm
               Net-Mail network or through the CRS network. Complete
               information is supplied in the registration packet. You can
               communicate directly with us for the price of a local phone
               call!


Complete Patch table listings

               Registered users now receive a complete listing of useful
               patch locations within NARC.

NARCCFG.EXE

               The configuration program is no longer included in the
               BBS release of NARC. This file is supplied only to
               registered users.


Bonus Utilities

               The registration diskette contains several other useful
               IDC utilities.

                               THANKS !

       I would like to extend a very special thanks to all of those who have
       registered their copy of NARC.
