RI
FUNCTION: Return from Interrupt Routine
DESCRIPTION:
The RI command is used to end the interrupt subroutine beginning with the label #ININT. An RI
at the end of this routine causes a return to the main program. The RI command also re-
enables input interrupts. If the program sequencer was interrupted while waiting for a
trippoint, such as WT, RI1 restores the trippoint on the return to the program. RI0 clears the
trippoint. To avoid returning to the main program on an interrupt, use the command ZS to
zero the subroutine stack. This turns the jump subroutine into a jump only.
ARGUMENTS: RI n

n = 0
