in thread regular expressions. help

Well, what I'm doing is taking the value of the data in the fourth field (in this example, it is gpa, but it could be a whole host of random letters strung together) and putting it into a variable. But, that isn't the problem I'm having right now -- the problem is getting the blasted thing to match and acknowledge that there is anything there.

    When trying to construct an re to match something, perl -de 0 can be very helpful. Set $_ to your sample data and then you can iteratively construct your re with x /blah/ (seeing if it matches and what matches at each step).
