A habit of mine is to not increment my do whiles.  Crash, make changes, run, infinite loop.  Repeat. 

I'm not a Unix person (I just code), but I do love recursion with GNU's Not Unix.  It's the most novel acronym I've come across.

Anyhoo, I'm curious.  Any COBOLs or FORTRANs here?  I heard they're a rare bunch these days.  But I wonder, what was the programming world like before COBOL?  Was it punched cards?
