Hi Aram, RS-274NGC as far as I can tell just doesn't provide for special functions. It does provide G01, G02, G03. Anything else is programmed by using that facility and programming externally. A few manufacturers have provided splines specially coded within their version of the interpreter ( Okuma comes to mind). More might do so if there were an universally agreed upon standard to representing the splines.
To get around this most people with special needs write programs in their favorite language that represent the desired function in G code usually as small straight line segments or as short G02 or G03 segments to interpolate the function to the desired accuracy. This is also true of most of the CAD programs; they output small segments to represent contours, etc. The developers of EMC2 have worked on making the short segment stuff work well and that is within the limits of the present interpreter. So my suggestion is to grab your favorite programming language and go to work. Check Jon Elson's page for an example of hole making. I occasionally write programs to represent contours that are curved in two dimensions. Not too difficult to do. You just have to pay attention to details. A little geometry/trig and a good loop can do wonders.
