I'm thinking the next round is going to be far more competitive now that we all know these little tricks.
1*(str) vs. -(str) ;Brilliant
MOD vs. substr,left,right ;Brilliant
$A=$=1 ;Brilliant, had no idea this was even possible in kix

I've got issues with if w/o endif though. Seems more of poor man's hack than a clever solution.

To Chris' point, it is amazing how similar the code is. Late yesterday, I started working on another recurisive solution that looks like a bastardized frankenstein of the MOD flavored code and the left,right,substr code. Couldn't bring it together though.
