Hi,

one trick is to allocate a lot of big variables in the autoexec
and clear them when you want space:

In the Autoexec:
SET JUNK1=12345678901234567890123456789012345678901234567890
SET JUNK2=12345678901234567890123456789012345678901234567890
SET JUNK3=12345678901234567890123456789012345678901234567890

in your batch file:
SET JUNK1=
SET JUNK2=
SET JUNK3=

Ahh.. and don't forget inyour config.sys to allocate enough environment.

Explanation: When you create a new shell, DOS allocates only little
extra space in the environment.

BTW: don't forget the maximum line length of 127 characters!!
