Ok I have forced myself to admit that 'C' has its place and programming a 24f in ASM is probably a bit of a stretch.... I need a pointer or two to a few basic guides to 'C' as I have always written in ASM all the way back to the Sinclair Science of Cambridge MK14..= .. (1979 I think) and a little bit of basic on a commodore pet (with a non qwerty keyboard) All suggestions gratefully received=20 Thanks Steve --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
