		           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.
