Does anyone have a cross-reference table for PBP commands to the # of clock cycles needed to execute that command?

Would be useful in timing critical situations to know which commands to use / stay away from.

Thanks!

none exist and there's a good reason for. How many different way you can write and IF THEN ELSE? FOR TO NEXT? WHile/WEND and so on?

you can use different methos to measure it, toggle a led before and after a statement block and measure it with a scope.

Start a timer before, stop it at the end, calculate the amount of tick then send it over serial to your pc or on a lcd.

Use MPLAB stopwatch

list is long...

EDIT: there's something to play with... say thanks to Darrel
