This is the simple fact that by so doing you are probably going to make it immensely difficult for anyone to later understand and successfully enhance your code, should that ever be necessary. One of the cardinal rules of good programming is that you should not use obscure tricks if you don't have to and if you do have to, you should explain as fully as you can what you are doing. I dare say renaming the opcodes of the 370 instruction set counts as an unnecessary trick. Michael Johnson "We are the Priests of the Temples University of Maine System of Syrinx.
