Recent machines are really excellent. Occasionally, it is good to take a break from knocking them, and remember - for example - the HP2100, which didn't have an integer subtract instruction. (You did "I-J" by: loading J: complementing it: adding one: then adding I. Yes, it didn't have a negate instruction, either.) From this perspective, RISC machines are actually featureful. -- Don D.C.Lindsay
