There's nothing to "work out". It's very easy. Just add:

use strict;
use warnings;

as the first lines in your program. That's it. Now sit back as it finds all your typo's for you, and warns about fishy things happening as it runs! Isn't that great? Isn't that what you were asking us for in the first place?

I think you get the wrong idea of our "attitude" because you don't know what "strict" is for. Your initial comment about "not worth it because of all the subs" also makes me thing that.

As for your formatting question, the concept is pretty basic: subordinate things are indented farther than its controlling logic or framing structures. Anything else is details and subject to personal taste. Just be consistant, and follow that guiding principle, and you'll be fine.

Yes, you will get the reception "use strict, then ask again after fixing everything it finds for you" if you post code that doesn't. Every time.

Good luck, and keep trying.
