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
The
routine and are re-activated after the end of the interrupt routine (see "Subprograms with
SAVE mechanism (SAVE) (Page 166)").
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
interrupt routine (SETINT)" (Page 124)) therefore activating additional interrupt routines.
They are triggered via the input.
