Now, we'll store the required numbers in registers R0, R1, and R2, then we’ll run the program, using Ç so that we can check that the branching occurs properly. It’s good practice with programs containing conditional test instructions to check that the program branches correctly for all possible conditions: in this case, if the income is less than, equal to, or greater than the test value.
