Summary: 

If you are using CP/M 3.0, you can use the "chain to program" BDOS 
service call.  It is bdos function 47.

You load a null-terminated command line into the default dma buffer, then:

You have reg C: 2fh
	 reg E: ffh if you want the ccpt to initialize the default drive
	        to the "current" drive and user number (rather than
		"reset" to default values).

Then call the BDOS (addr 5 was it?).

Don't know off hand if this call works in 2.2 or not.  Haven't worked
with that version for a few years now.
