The Data Restrictions section had the answer. The NULL values were what was killing me. I'm gonna look into DBD:AnyData.
I hate to keep asking questions, but I'm a Perl Novice. These files that I am working with could contain any number of NULL values. What would be the best way of handling these?
I think I got it. Now I just have 1 last question. How do I get it to output in csv format?
