N: Subroutine number
Specifies the subroutine number between 0 and 1023 decimal.
Note For CJ1M-CPU11 and CJ1M-CPU21 CPU Units, the subroutine number must be between the range 0 to 255
decimal.
Note Global subroutine numbers and regular subroutine numbers (SBS instructions and MCRO instruction operands) are
shared (do not use the same number for a global subroutine and a regular subroutine).
