List,

Many modern CNC Gcode dialects use G20 and G21 for inch and mm,
respectively.

As to the question, both stepster (basic) and EMC (C++) include Gcode
interpreters which could be a starting point for such a program. It
may be that a 'full' interpreter is not needed, since you really just
need the coordinate parameters to change.

I'd sure look for the control units option first!

In some older controls, it is a setup parameter, and can be changed
only IN the setup, and NOT 'on the fly'. And on some machines the
display will be incorrect, BUT the file WILL process properly!

Hope this helps.
