Advanced math was a term I used. Meaning more than just a simple scale
or add - although that's most of what I ever need.

I have used subs to program tool changes and added this into a custom
post processor.
I like subs and loops to keep code small and compact.
One of my CAM systems (FILOU) creates large files when milling pockets
in multiple passes. I now use multiple passes using a while loop instead
of repeating a lot of lines of G-code.

Up to now I have not needed this but it would be nice to know how to
feed hold, spindle stop and jog during a program.
My current machine is large, slow and has an open construction allowing
me to clear chips with a brush while running but I may be doing a
retrofit of a machining center where this is not what I like to do
(somehow I value my fingers too much for this :-) )
Regards,
Rob
