Description
When the subroutine is not being executed, the instructions are treated as
NOP(000).
See 3-18-3 SUBROUTINE ENTRY: SBN(092) for examples of the operation
of RET(093).
Calls the global subroutine with the specified subroutine number and exe-
cutes that program. The same global subroutine can be called from two or
more tasks.
GSBS(750) is used in combination with GSBN(751) and GRET(752), the
GLOBAL SUBROUTINE ENTRY and GLOBAL SUBROUTINE RETURN
instructions.

GSBS(750) calls the global subroutine with the specified global subroutine
number. The global subroutine is the program section between GSBN(751)
and GRET(752). When the global subroutine is completed, program execution
continues with the next instruction after GSBS(750).
