Now, we'll store the required numbers in registers R
0
, R
1
, and R
2
, 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.
