I have to admit to simply being lazy on this one, since I could have easily looked it up myself. Sorry to bother you with something so trivial.

I've gotten spoiled by how easy it is to ask questions here. I will try to be more respectful about not wasting people's time.

Mostly I use perl to create input to spreadsheets, so most of my variables are simple arrays.

That answers my question. Thanks again for all your help.
