NOTE:	on 4/19/89 ff was changed to inscat by Sean Hames
	ffact and inscat are newer versions of ff.
	 v and xarg are two versions of the same thing and they are used
        along with inscat or ffact.
        inscat and ffact are not complete for all the elements, so care
        must be taken in the utilization with either v or xarg.
