Timothy:
Thank you for your response. As you can probably tell from the structure of
my loop, I am by no means a Perl professional or expert--could you please
possibly explain to me what is going on in the first loop you post? I can't
quite unpack it. I understand that you're adding some sort of index to each
file's fields, but it's murky.
If you don't have the time to do that, could you perhaps point me somewhere
where I can read about this sort of algorithm?
