Bruce,

Wow, what a lot of effort on your part - thanks very much. I will now re-fire up MPLAB and give it a detailed run.

I do take note of CL's comments about this being a PICBASIC site but most entheuastic PBP users will want to experiment with ASM - for fun and speed?

I know that every minuit I've spent on ASM in MPLAB had added greatly to my ability to write software in PBP.

Perhaps there is space for an 'ASM' sub-section in this forum? I can understand that most newcomers will not be interested in this lower level stuff but it seems essential to make the most of PBP.

We are in the middle of a heatwave here in West Australia - almost no rain for 3 months - too hot to do much outside so plenty of key-board time.

Thanks again for your input.

Regards Bill Legge
