Not modal. Acts once on the line where it is commanded.
Example program
G90 G54 G00 X0. Y0. (POSITION)
M98 P1012 L3 (RUN PROGRAM O01012 THREE TIMES)
G00 Z1. (RETRACT)
M98 P1012 L3 (RUN PROGRAM O01012 THREE TIMES)
G00 Z1. (RETRACT)
Example is in inch. Check offsets and clearances first.
Watch out for
- The subprogram must be loaded on the control and end with M99.
- Use G65 if you need to pass arguments.
On lathes: Subprogram call

Example program
M98 P100 L4 (CALL O00100 FOUR TIMES)
M30 (END MAIN)
O00100 (SUBPROGRAM)
G01 U-.1 F.01 (STEP IN)

- File paths are case sensitive.
