2] The program is executed when R000 is on and R001 is off
CAL 0 is executed, then the subroutine 0 program is executed.
CAL 1 is not executed, the subroutine 0 program is terminated and the
execution is returned to the code following the CAL 0.
3] The program is executed when R000 and R001 are both on
CAL 0 is executed, then the subroutine 0 program is executed.
CAL 1 is executed, then the subroutine 1 program is executed.
The subroutine 1 program is completed and execution is returned to the code
following the CAL 1.
