Dolphin support for step/direction?

With all the chat about Dolphin (and since I myself am looking at
what cad/cam to use for soon to have cnc conversion) I thought that I
would take a look at the demo of Dolphin PartMaster. 1st off it's
relly nice (IMO); I've tried many programs (demos) and the only down
I've seen (in my limited playing) is the (apparent) inability to
specify dimentions with the keyboard (It's hard to be accurate with
the mouse on small stuff). The demo fails to start the mill program
from the menu (error dialog that won't go away) but the real killer
is the generated NC. If your using step/direction what option
what "post processor" should I use?
