perl will close the file when it exits but I guess if you put that close between the loops it might make sense.

And when you're working in perl you don't call associative arrays "associative arrays". You call associative arrays "hashes". And when you write a perl routine you always try to sneek them in where ever you can. This book says: "Until you start thinking in terms of hashes, you aren't really thinking in Perl."
