Using double quotes is best because the command won't break if the
environment variable contains a space....

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.
