Phillip, >> I couldn't work out how to do 8 byte multiply/divide well, if you got Knuth Vol. 2 `Seminumerical Algorithms', there is extensive discussion of this matter. And yes, while multibyte addition/subtraction is quite simple using the ADDX and SUBX commands, multiplication is not that easy, and division is the hardest thing to deal with. I wrote these routines some years ago. They are not the best way to do it, I'm sure, but if you are interested to have a look at this dirty code, I would like to mail it to you. – wkc – … via AP from Hamburg, Germany
