Actually, it's not how much you've allocated that matters, but how much is 
actually in use.  When you EXEC a program, DOS creates an environment block 
that is just large enough to hold all the current variables plus the
program's full name.  The amount you allocate via /E only sets the size of the 
environment for the initial copy of COMMAND.COM.
