BRZ - branch if the outcome is 0. BRP - branch if the outcome is positive or zero. Now, let's use the LMC to determine the bigger of two numbers by using the above loops; the output must be the bigger number regardless of its order of input.

What is BRZ and BRP in LMC?
BRZ - branch if the outcome is 0. BRP - branch if the outcome is positive or zero. Now, let's use the LMC to determine the bigger of two numbers by using the above loops; the output must be the bigger number regardless of its order of input.

Can BRP be used for subtract instructions that cause negative results?
Note: the contents of the mailbox are not changed, and the actions of the accumulator are not defined for subtract instructions that cause negative results -- however, a negative flag will be set so that BRP can be used properly (see below). Copy the value from the "in box" onto the accumulator (calculator).
Is there a way to execute BRP if branch is zero?
BRZ sets instructions to be executed specifically if Branch is Zero, but BRP does count zero as a positive number, so the only way around this is to contradict the BRP instructions with BRZ instructions.

What is BRP in Little Man Computer?
They are: BRA - branch always. BRZ - branch if the outcome is 0. BRP - branch if the outcome is positive or zero. Now, let's use the LMC to determine the bigger of two numbers by using the above loops; the output must be the bigger number regardless of its order of input.
Does BRP include 0?
BRZ sets instructions to be executed specifically if Branch is Zero, but BRP does count zero as a positive number, so the only way around this is to contradict the BRP instructions with BRZ instructions.

Can LMC multiply or divide?
The LMC can add or subtract numbers, but it can neither multiply nor divide. The obvious drawback actually makes programming even more interesting: the multiplication, in fact, can be carried out with the aid of addition!
