   In versions of DOS prior to 4.0, there was a well known patch location
   in COMMAND.COM that allowed you to change the default environment size.
   The default was usually something like 160 bytes (0A paragraphs), which
   is ridculously low.  However, it was a simple matter to use DEBUG to
   patch it to something reasonable (e.g., setting the byte to 30 would get
   you a 768 char [minimum] environment, in all your subshells.)

I can't tell you the exact location, only for the german version which 
wouldn't help you very much, but I remember that the unexpected problem
with this patch for DOS 5 was, that the default environemnt size is now
256 and not 160, so you have to search for something with hex 10 and
not hex 0A to locate the patch point.
