in reply to Making a hash of arrays from a datafile

Your example look fine, just use print Dumper(\%DATAHASH);. and use my instead of local until you know the difference.

    *slaps self in head* right, of course. That's why the Dumper wasn't working. With respect to local v. my, no, 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. Also, the data will never contain commas, so I'm not too worried aobut getting bitten in the arse there. Thanks!

      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.
