A simpler way is just to create a variable called FILLER that takes up lots 
of space in your first loaded copy of COMMAND.COM; when you need space in a 
child shell, get rid of FILLER.

e.g. Use the option to COMMAND in the SHELL= line of config.sys to get a 
great big environment block, then in autoexec.bat 

  SET FILLER=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

and in a child shell

  SET FILLER=
