Branches to program line 08.

Recalls 20% tax rate to X-register.

Calculates tax.

Sets calculator to Run mode. (Display shows results of running of previous program.)

Now, we'll store the required numbers in registers R0, R1, and R2, then we’ll run the program, using Çso 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.
