Ralf,
i ran this code
very interesting results, how? i would assume that the b buffer would
sit on the stack past the a buffer as it was declared afterward, and
also i'm confused of how assigning string lits to b beyond it's
allocation would affect a?  and wouldn't a still have a term null char?
obviously this is the problem everyone speaks of, is there a logical
explanation?
thanks,
steve
