Anyways, if I add a bad character into that, it succesfully spits out
"false". If there are no bad characters, it segfaults. I can't figure
it out right now, but it has something to do with the last two terms
of the array (its fine up through i=62 for a 63-length array). When I
run it through GDB with a breakpoint on the loop, it says
"EXEC_BAD_ACCESS". When I run it straight, it says "Error 10
(SIGGBUS)". Any help would be appreciated.

Thanks,
Andrew

Oy, I just fixed it as I posted this (When you know me and my code
better, you'll realize I NEVER am able to fix my own problems until I
ask someone, then it hits me. It drives my IRL teachers nuts)

The problem was I made the array 63-length for all the allowed
characters AND a "bad" character. But there are only 62 good
characters, so it choked when the last entry wasn't defined.

It's alright, that happens with me too. Just ask Alastair...
