Subroutines

GSBN/GRET
• Place the global subroutine region (GSBN(751) to GRET(752)) in interrupt task 0 just before the
END(001) instruction. When two or more global subroutines are being used, group them together in
interrupt task 0 after the end of the main program. If part of the main program is placed after the
global subroutine region, that program section will be ignored.
Example Programming
• The step instructions, STEP(008) and
SNXT(009) cannot be used in global
subroutines.
When CIO 0.00 is ON in the following
example, global subroutine 10 is executed
and program execution returns to the next
instruction after the GSBS(750) instruction
that called the subroutine.
