Using LMC code for an assignment
Posted on 2009-05-13
I have to test a sequence. I can enter the first few numbers but stuck on if test number is greater than the second? I can enter and load numbers, but to test if one is greater than the other, do I use BRZ? if greater than zero then what? I have the site atkinson.yorku in front of me if that is all I need, I just would really like some clarification as to how to use it.

Yes, you'll probably use a BRZ, you don't know the context yet.
If you subtract A from B and the result is zero, what does that tell you about the relationship between A an B?
Now, if the result is not zero and positive, what does that tell you?
So, you might do something like:
1) if a-b is zero go do they're the same
2) if it was positive, A must have been larger, so go deal with that
3) Otherwise B was larger, so deal with that.
So, it looks like you'll have both BRZ and BRP.
