Branching

Branch - This only changes the flow of execution when a condition is true

Branch = Jump

It is not efficient to code the destination and the condition in machine code

So the condition is coded separately to the jump

Accumulator

Status/Condition Bit stores the effect of a the outcome

This allows for flow control based on a conditions outcome

How to do A=B

Remember break it down into two instructions

1. A-B

2. Branch if 0

How to do A<B

1. A-B

2. XOR the most significant bit (Sign Bit) and the Overflow

3. Branch if ...
