I still disagree with you Hans but I see no end to this interchange.
If you don't believe me, go try it, just don't read the tutorial and comment on what you think is correct because it's posted in the tutorial. I already pointed out the error in the tutorial on LCD's. I respect Creig and others here but WE ALL make mistakes. Just try what you say before arguing the point. I do, almost everyday. Read what the person asked for advice, what I said was true and will work, I have done it many times. Although I don't consider myself a software expert I am highly qualified to write assembly language routines. You can cheat the stack many ways and do exactly what Stefalus wanted. Again, I would not suggest doing this but if you still don't believe me that what I said works, then I suggest you, go try it on your microP or your simulator. There is no point arguing this with you if you never tried to do this. Ok, maybe this will help you to see this better Hans. Off load the stack of all bytes put there by sub's, value stores and return address of the high priority interrupt. Then with some flag set, You add back on to the stack the new address you want to go to. Then do your return from interrupt command. The cpu doesn't care where it came from, it knows the address is on the stack and knows where it should return to, and it doesn't care what this address value is. You can send it anywhere you want.

Hans I'd rather not argue any more on this subject, it's a big waste of time for me. If you still don't understand this, then, YOU WIN, I'M WRONG and I concede to you. I feel just like Bush dealing with Al Gore. Sometimes you just can't win no matter what you say or do.
