The school where I'm teatching CAD and CAM has recently finally obtained a CNC machine, a small Kosy A5 mill. I haven't had any luck with the postprocessor I'm writing for this little thing, my biggest concern right now is how I could get the Code Wizard to repeat the words at the beginning of every line, here's a short example of the code accepted by Kosy A5:

I am able to get rid of the line numbers and I'm also able to get most of the other things right but my testing has come to a halt because of this. Any advises?
