Thanks, tilly, that's good advice! I do use strict and warnings in all my code, but since I was just posting code fragments I didn't think to do so.

Whenever I receive any perl code, before doing anything I run perltidy on the code and add "use strict" and "use warnings". It's easily worth the effort.
