[Is there a reason for this anymore?]

	As a user of the Desqview multi-tasking software I was very
much interested in the recent discussion of the environment size
issue.  It seems that starting the command.com command interpreter
from Desqview causes the environment size to be reset to the pitiful 160
byte default.  The fix described by someone was to perform the required
modification to the copy of command.com residing in the Desqview directory
thereby increasing the default size.  But alas, DOS 3.2 was not included
in the list of fixes that I had compiled from this newsgroup.  Perhaps I
missed that fix or perhaps no one has bothered to post one so I went ahead
and debugged the thing.  Here are the results:

/* start fix (<cr>=carriage return, enter or whatever) */
debug command.com <cr>
-e 0d4f <cr>
xxxx:0D4F   0A.32 <cr>		/* debug prints the 0A. and you type the 32 */
-w <cr>
-q <cr>
/* end fix */

	The 0A is the hex number of 16 byte pages that dos will allot to 
environment by default.  32 pages is 50 pages or 800 bytes of environment
space.  Use whatever amount you feel you need.  I must confess that this
is essentially the same fix as the 3.1 fix that was posted many moons ago.
It was, however, a different address in the code and I did spend many minutes
looking for it.  If you feel that this information is of some help to you
or your company, please feel obligated to send to me a cash gratuity in
multiples of $16.00 using only USA hexadecimal currency (via Email). |-}

P.S. I must (under duress) also give credit to an associate, Jake Kjelstrup
(pronounced "kludge strap"), who was able to save me many more minutes by
giving me the appropriate commands to debug.   I do detest manuals and his
help was nearly invaluable.
