Greetings Netlanders!

I'm having trouble setting my PATH to a length larger than an small 
(127?) number of characters.  According to the DOS 3.3 manual, that 
is suppossed to automatically expand.  Is this really a hard limit?
A mistake on my part?  I've changed the SHELL command (as someone 
posted here before - I'm sorry I don't remember who) to bump up the
environment area size.  There seemed to be no effect on PATH.  Anyway, 
what follows are edited copies of CONFIG.SYS and AUTOEXEC.BAT.  Please 
help me get a longer PATH.  I think the Environment area is OK.

-----------------------------CONFIG.SYS--------------------------------
COUNTRY=001
BREAK=ON
DEVICE=VEMMSIME.SYS M=24
DEVICE=VEMM.SYS D=24
DEVICE=ANSI.SYS
DEVICE=VDISK.SYS 384 512 64 /E
HANDLES=20
FILES=23
LASTDRIVE=H
BUFFERS=20
STACKS=10,128
SHELL=COMMAND.COM/E:512/P


-----------------------------------------------------------------------

-----------------------------AUTOEXEC.BAT------------------------------
	Note:  I added the carriage return in the middle of the PATH
		statement so that it would fit within 80 characters.

That's the whole mess, less some TSR installations, extraneous commands,
and comments.  I've already looked at the DOS 3.3 manual, the "DOS Power 
User's Guide", and the "IBM PC-DOS Handbook" with no real results:

    1.	Yes, I know I can do a SUBST command, but I would prefer another, 
	cleaner way (if possible).
    2.	Yes, I know the SHELL command can expand the environment (I've
	already got it upto 512 (see above).

Please, no flames for overtly stupid settings - VAX/VMS is my forte.
But I sure would appreciate hearing some guidance from a few of you 
experts out there.  If you wish, email to me and I will summarize.

Thanks,

George
