Whoa, am I beet-red! I'll try not to post to comp.lang.c for another
month in repentance. Even the second attempt at COF is way wrong. 

Last try: (though this one doesn't look as horrible as the one above)

	if ((A = f1()) - 2 || (A = f2()) - 3 || (A = f3()) - 4)

("not to put too fine a point on it," as the British say.)
