Wouldn't using op<= instead of op< > complicate the implementation of STABLE-SORT? ) But wait a second, isn't (< a b) = (not (>= a b)) = (not (<= b a)) at least on integers? So both < and <= are the **same** machine instruction, except you have to flip the arguments, and change the destination label, but this has no run time "cost"... Marc
