I have to patch COMMAND.COM for a larger environment because when
DESQview creates a DOS window, it fools COMMAND.COM into thinking 
that there were no previous environments.  In other words, DESQview 
does not allow the DOS window to inherit any enviroment variables 
from your previous DOS environment; nor does it create an environment 
with the same size as your previous environment -- it creates an 
empty environment with the insufficient default size hardcoded in 
COMMAND.COM. 

The solution is to patch COMMAND.COM for a larger default size and
for the 'Program...:' parameter in the DOS window 'Change a Program'
screen, specify a batch file that SETs up your environment variables.

Without this patch, I would not be able to run programs, that require
many environment variables, within a DOS window, such as, Brief and
uupc.  Oh, I guess I could create *another* command shell within
the DOS window using the '/E' parameter, but this consumes 6k of
precious RAM (RAM is precious when you begin to partition it within
DESQview).  

By the way, can anyone, who has bought a 'Charge Card' memory board 
for use with DESQview, tell us if it works as advertised?
