in reply to Dynamic array names

This is one of the Common Beginner Mistakes. (No offense, any experienced programmer who claims not to have asked the same question once is either Donald Knuth or a liar.)

If you have a list of items to process and you don't know how long the list will be at compile-time, use a stack. In Perl, that's as simple as using push to add another element to an array. That's exactly what arturo suggests.

Attempting to keep track of a bunch of names generated on the fly can be tricky, and in this case, it's probably completely unnecessary.
