Calls the subroutine with the specified subroutine number and exe-
cutes that program.
N
Indicates the beginning of the subroutine program with the specified
subroutine number.
N
Indicates the end of a subroutine program.
Sets up interrupt processing for I/O interrupts or scheduled interrupts.
Both I/O interrupt tasks and scheduled interrupt tasks are masked
(disabled) when the PC is first turned on. MSKS(690) can be used to
N
unmask or mask I/O interrupts and set the time intervals for
S
scheduled interrupts.
Reads the current interrupt processing settings that were set with
MSKS(690).
