Would someone please explain how to convert the output of the Drill 
file to cnc g-code?

I'm using Ares from Labcenter to generate the cadcam output  code.  I 
believe it is in rs274x format.  The code has no Z axis motion and no 
decimal points like I'm use to seeing in the G-code I normally feed to 
my cnc mill.  

There is an example of the code that Area's spits out (X+004314Y-
025547).  Is this called Excellon format?  

This is what I would type to drill a hole at x=1, Y=2, 0.2 deep: (G01 
x1 y2 z-0.2) using G-code.

Thanks
