Yeah, M98 subroutines work in Mach 3 too.
Machs m6start macro works in the background, just a vbscript that runs when the m6 t# code is used.

So from this, I gather you must place the sub at the end of the program? not so conveinient for multiple programs running the same sub... is this common with other cnc controllers or am i misunderstanding?
