Subroutines Section 3-19
Precautions When the subroutine is not being executed, the instructions are treated as
NOP(000).
Place the subroutines after the main program and just before the END(001)
instruction in the program for each task. If part of the main program is placed
after the subroutine region, that program section will be ignored.
Note The input method for the subroutine number, N, is different for the CX-Pro-
grammer and a Programming Console. Input #0 to #1023 on the CX-Program-
mer and 0000 to 1023 on a Programming Console.
Be sure to place each subroutine in the same program (task) as its corre-
sponding SBS(091) or MCRO(099) instruction. A subroutine in one task can-
not be called from another task. It is possible to program a subroutine within
an interrupt task.
