Mark I, too, grew up on the 6502, and the PIC is a LOT different. As a RISC processor, and a Harvard Architecture processor at that, much of the cool indexing instructions of the 6502 are lacking. Maybe the most confusing, though, is that the add and subtract aren't nearly as complete. On the other hand, like the 6502, it is very logically laid out, and with only 35 instructions to learn, it's pretty quick to get your head around it. And even though it is lacking the 6502's X and Y registers, there are some rather perverted ways to get to the same place . --McD _______________________________________________ http://www.piclist.com View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
