: It depends on what exactly he was having trouble with. This is certainly an
: option, but my guess is that he wants to be able to run a batch file and be
: able to set new environment variables, but then return to the original
: program afterwards. If this *is* what he wanted, then there is a solution.
: Say your environment is 1024 bytes long (set with COMMAND /E:1024) and of
: that 800 bytes is used (224 bytes free). The problem is that when you run
: the batch file with system() or whatever, the new instance of COMMAND.COM
: doesn't get the /E:1024 parameter (because system() doesn't specify it), so
: DOS assume you want the default 160 bytes. But because 800 are already in
: use, you get all 800 bytes without any extras. The result, you don't have
: those extra 224 bytes.

: The solution I use is a small TSR program I got from someone in this group
: (I can't remember who offhand - it's in the docs - sorry!) which basically
: fixes the problem. Don't ask how, it just does. I'll mail/post it if you
: like - I have the authors permission to do so.

Why can't you just take and system("Whatever.bat");
