5 min after posting this, I got it =)
Basically I'm putting up a series of programs for people to go through, find a serious error, fix it, then run it to get a hidden letter.
The only 'real-world significance' of this, would be for debugging purposes, without taking a shortcut in easily reading the code (unless you spent the time, but faster to fix and run).
Thanks aswell -- did this in a rush, so I didn't put in a few of those things you pointed out ($bar
$i instead of @...). Thanks again.
