.h in assemblym works beautifully as far as #define, sfr and sbit being useful in assembly. Now I have a case of conditional compile that I need reflected in an assembly module. I have tried to make the assembly IF and $IF work based on a #define. Using IF it works if I do a #define 1 or #define 0, that, however wil require replacing all #ifdefs in the C. $IF seems not to react to #define any suggestions? Erik
"as stated earlier, somehow my assembler manual got purloined" ...and the dog ate my homework. I find the online manuals quite easy to use as they are structured pretty well. Start from the main contents list and follow your nose.
