Creating an interrupt routine

Create interrupt routine as subprogram
The interrupt routine is identified as a subprogram in the definition.
Example:
Program code
PROC LIFT_Z
N10 ...
...
N50 M17
Save modal G functions (SAVE)
The interrupt routine can be designated by defining with SAVE.
The SAVE attribute means that the active modal G functions saved before calling the interrupt
routine and are re-activated after the end of the interrupt routine (see " Save modal G
functions (SAVE) [Page 172] ").
This means that it is possible to resume processing at the interruption point after the interrupt
routine has been completed.
Example:
Program code
PROC LIFT_Z SAVE
N10 ...
...
N50 M17
Assign additional interrupt routines (SETINT)
SETINT instructions can be programmed within the interrupt routine (see Assign and start
interrupt routine (SETINT, PRIO, BLSYNC) [Page 122]) therefore activating additional
interrupt routines. They are triggered via the input.
