  3. I have a program that calls the mouse_get KERNAL function in a loop. It takes the return and converts the values from HEX to BCD. When have my program call the convert function the mouse position "freaks out" jumps all over the screen when I move the mouse and my program does not work correctly. I have been messing with it and I have found that I have to start the convert function with SEI and end it with CLD and CLI to solve the problem. It seems the mouse interupt routine is not expecting that sometimes the processor is in BCD mode. ROM version R41. Thank you. Doug.
