I'll soon push an update to the m98/m99 feature branch that adds
Fanuc-style main program numbers. See Smid's "CNC Programming Handbook
3rd. Ed.", p. 66, describing how main programs may begin with numeric
O-words in the same way as subprograms (but end with M02 or M30 instead
of M99). This is an extra feature for compatibility with some CAM
software that generates G code for Fanuc controllers. Example:
O1000 (MY PART PROGRAM)
G0 X1 Y2
M30
Thanks-
John
