Jim:
	The 128 byte limit is, I believe, the maximum command line length.
You can extend the path up to the limit of the environment size with:

	SET PATH=%PATH%;new_directories

Note that this works only from within a batch file; from the command line,
DOS doesn't expand the %PATH% properly.  I like to keep a batch file called
ADDPATH.BAT that contains the single line:

	SET PATH=%PATH%;%1

To call this from AUTOEXEC.BAT (or any other batch file), use:

	COMMAND /C ADDPATH new_directory

To expand the keyboard buffer, try VISITYPE from the 28 OCT 86 (vol 5 no 18)
issue of PC Magazine.  It provides an 80 character buffer and displays the
yet-to-be-used characters on the first line of the display, so that you can
actually SEE what you've entered.  Get it from their BBS at (216)696-0360.

P.S. I *love* DOS.  It gives one so many opertunities to say "Now why in
hell didn't that work (:-)?"!
