As a side note, don't use chop to get rid of newlines. I see this all the time in programs and it makes me cringe. You want to use chomp.

chomp will only remove the last character if it's a newline. Consider the following "harmless" code: 

#!/usr/bin/perl -w
use strict;

while (<DATA>) {
    chop;
    print "$_\n";
}

__DATA__
this is a test
this is another

You can't see it in the above code, but I deliberately did not hit "Enter" after the last line. I even hit backspace a few times to ensure that there was nothing after the word "another". The result?

chop happily removed the "r" in another. chomp was designed for situations like that and should be used where appropriate.
