Oops! I must've missed an earlier part of this thread, because I didn't realize the
question was for 9x. My apologies.
Andre's right. My solution only works on NT/2000/XP.
Andre's solution will also work on NT/2000/XP, but I would use double-quotes, instead
of braces (although, they will work), since, in 2000 and XP, you can use the braces or
parentheses to separate the
IF clause from an ELSE clause.
If not "%somevar%" == "" echo Variable exists

I believe that IF DEFINED only works on NT boxes, not 95/98. If it is an all NT
environment, then it is OK. Otherwise, use syntax as follows:
If not {%somevar%}=={} echo Variable exists
The { sign can be replaced with quotes, but to each their own. The double = is very
important, otherwise you will tear out every last strand of hair on your head ....

Subject: Test Whether Variable Exists
Hi,
This should be an easy one but I cannot find the answer after hours of searching. I am
looking for a way that I can test whether a variable exists and then take action on
the result. This is for use
in a login script - not a KIX script. I don't want to add, change or delete the
variable in anyway, just check whether it is there or not. Can anyone suggest a way?
Thanks, Simon Butler.
