In-Reply-To: <[log in to unmask]> Hi Pete, OK, I see it now. That's way too many files hit for me to absorb. I guess I don't understand why the massive change. Theoriginal setup was *supposed* to prevent the expansion of the macro if NODEBUG was set and that shouldn't have caused any compiler problems. So, I don't understand the change at all, I guess. Gerri what was the actual problem? Andy
