M-function Warning (formerly Error)

The M124 M-function, when executed within an NC program on the Heidenhain TNC 640 control, now generates a warning instead of an error message. This modification allows NC programs containing M124 to complete execution without interruption, even if the condition associated with M124 is met. This changes the operational impact from a program halt to a notification.
