I don't quite understand your question, but a small unrelated thing: Instead of doing this: 
my $num = 0;
for (1..5) {
    $num++;
    .
    .
}

Do this: 
for my $num (1..5) {
    # You can use $num in the loop, and it gets
    # increased automatically
}

[download]
This keeps the $num variable nicely local to the loop.
