Yeah, this single instruction set fascinated me too, since the early 90s when we talked about it in the Munich Forth group meetings. It has ZERO opcodes - because it would be always the same :) But there *is* a cheat. All real work is done by hardware at given addresses where values are moved to and fetched from. Also, code gets very large, because each instruction takes up 128 bits (two addresses, thus two words on a 64-bit machine). > Happy Easter and keep away from Windows and other viruses! Same to you, and everybody else! ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
