Thank you for your quick response, it worked. I checked the "Immediate Addressing" document in the tutorials, but it does not specify how to do this in binary.

Is this even possible? While specifying a hex value does work, it means I must convert a binary value to hex everytime - I'm slow at this. It would be much easier for me to visualize if I could MOV P2, 11100001. Could you tell me the correct syntax for this also?
