Hi Jan.Erik... Yes... I am (old) electronics engineer, so I really understand the mechanics of the RMW problem. After 35-odd years with various microprocessors, I've had my share of (even stranger) problems! > Now, it you are BSF'ing a pin that is configured as an > analog input, it *should* show as "0" in the simulator > because that is how the hardware sees it. But *that* > is *not* a RWM issue ! It's absolutely normal. :-) Yep... But the A/D _was_ switched off. > Have you given them a reproducer? > That is, actual code that shows the problem? I sent them the code, and I even sent them a screen grab showing actual single stepping through the execution and showing the results. I tried to re-open the issue, but didn't find how. So I re-submitted the report. John --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
