Temporary End (TND)

The TND instruction conditionally ends a routine.
When enabled, the TND instruction acts as the end of the routine. If the TND instruction is in a subroutine, control returns to the calling routine. If the TND instruction is in a main routine, control returns to the next program within the current task.
