in reply to Perl & modulus

Exactly what I needed. Thank you!

I am trying to perform a loop, it counts from 0 to $i, and it should do something every $x times, while still looping. Modulus is what I needed.

I just didn't know it was the solution to both of my questions :)

    Here is a nice chunk of code that uses modulus to control looping: 
        my ($returnNum)        = 0;
    for my $block (@blocks) {
        printf ("%-15s ", $block);
        print "\n" unless (++$returnNum % 5);
    }
    print "\n";
