        Hopefully you'll forgive a newbie question.  But first, let me
state what I understand you to be implying.  If I understad, you're saying
that the StrCmp works assuming that the text output of the fgrep is in the
variable $returnvar.
        Now for the question: is $returnvar a special variable that is set
to the output of the previous shell command?  If not, then how do I set
it?  I've looked in the likely places I could find in the manual, and
couldn't find anything.

        Thanks,
