Function
 SBN
 RET
When program execution reaches RET(093), it is automatically returned to the next instruction after the
SBS(091) instruction that called the subroutine.
Precautions
• Place the subroutine program area (SBN(092) to RET(093)) in the same task as the SBS(091)
instruction of the same number. Subroutines in other tasks cannot be called.
SBN(092) indicates the beginning of the sub-
routine with the specified subroutine number.
The end of the subroutine is indicated by
RET(093).
The region of the program beginning at the
first SBN(092) instruction is the subroutine
region. A subroutine is executed only when it
has been called by SBS(091) .
