As far as I can see, there's no built-in MOVLF (move literal to file) instruction, at least on the 18F6680 I've been working on. I know it's hardly a problem to load the literal into W first, then move W into the desired file, but why would they fail to design such a useful one-step function? have fun Matt -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
