Binary Subtraction

[Pa|2a|)oX]

This program took me a shorter time to make because I knew what I was doing now.

This uses ones and twos compliment to subtract digits, and as so is inherently only able to subtract a maximum of 7 bits (127 in decimal).

No shortcuts, and this one is relatively well error trapped, it will tell you if you overflowed, and if you entered a wrong answer of some sort. The binary input section is not error trapped, only 1s and 0s may be inputed or it will crash.

Thanks

its pretty good although errortrap would have been nice
