Subroutines
What Are Subroutines?
A subroutine is a program written between the SBN(092) and RET(093) instructions in a special subroutine
area. A subroutine is called from the main program using the SBS(091), MCRO(099), or JSB(982) instruction.
Subroutines can be used in the following three ways with the FQM1.
Using Normal Subroutines
A normal subroutine is written between the SBN(092) and RET(093) instructions and called using the
SBS(091) instruction.
1. Write the program to be executed between SBN(092) and RET(093).
2. Set the subroutine number for the operand of SBN(092).
3. Call the subroutine using SBS(091)
