Programming lathe with radius numbers

[mudwhump]

How would I set the lathe module to write programs in radial instead of diametric mode. The controller (Mach2 turn) that I'm using runs using radius instead of diameter numbers. Is there a conversion I would input. I tried changing the X scale to .5 in Setup Coordinates, but that didn't have any effect

On the drawing window: Go to File => Environment. Click on the coordinates tab and uncheck the Y = Y*2 option. That will out you in radius mode.
