Comparing variables....

I know I am just piling on the mail, but one more thing...

I sucked a file into a variable using:
VAR = `cat myfile`

Now I want to check to see if a variable (VAR2) exists within the file.
I've tried things like
* FILE ?? $VAR2
But I just don't know the syntax well enough to get it right.
I want a complete match.  VAR2 must be nested within FILE for the condition
to succeed.


Thanks
