in thread Making a hash of arrays from a datafile

I know what I'm doing here, the DATAHASH is actually declared elsewhere (I was including it here for clarity) and is referenced my multiple subroutines once the data is first read in.

This doesn't sound like a compelling reason to use dynamically scoped package variables instead of lexicals. I hate to sound too persnickety, but it's usually advisable to use lexicals by default, and only use package variables when absolutely necessary. So far, you haven't even demonstrated a remote necessity, and your assertion that you "know what [you're] doing" isn't very convincing.
