Okay before I get too verbose, I should say that I believe (not sure) I'm using 5.6.1. (tried manning to find perl version, but no luck - also checked perlfaq). The book I am learning from is Laura Lemay's "Perl In 21 Days" by sams. The code example is one I entered by hand from the book and it can be found in the "Day 9" lesson.
