RE: EXC/ x<>Rn for stack efficiency
I've been trying to figure this out and I'm getting confused and forgetting the stack at the exchange steps. So, please help me. Maybe you've already responded with the answer. But, the ends I'm trying to accomplish removes the former value from the stack and leaves the exchanged value on the stack with Y, Z, and (if possible) the T registers intact.

All I'm trying to do is leave the exchanged value in the X register without the forner register content in the Y register.

Perhaps I shoud have been clearer to the point of exact in my original post. Sorry.
