I know how to do it in a batch program, though it doesn't have much to do
if %ABC%=XYZ goto ALREADY_DONE
ECHO I just set the environment variable
REM do other stuff too if you want
ECHO The environment variable was already set.
It's cumbersome and there's probably a more elegant way, but you could try
using a 'system' statement (I have not tried this, and I don't even know
if it works outside of a batch file)
system("if not %ABC%=XYZ set ABC=XYZ");
Don't just hit "reply" - my E-mail address is bogus
to avoid automatic browsers from sending junk mail.

Actually, even this doesn't stop all of them ...
