  	@(#)mvsCpRep1Arg.c	1.8.1.1	Date:1/22/91
  	Author: TAT
	History:
	   03/30/90 SJS Add to sccs tree
	   07/31/90 SJS match index with resource by look up
	   08/01/90 SJS our internal XmStrings are regular strings and
                        XmStrings in Arg lists are *really* XmStrings
	   09/20/90 SJS use define for NON_EXISTENT
	Calls:

	Summary:
		This function places 1 argument into the args array
	used in XtSetValues() calls. If the named resource exists in
	the array, the new value replaces the old value. If the named
	resource is new, then it is added to the end of the list.
		Any resource that is replaced is appropriately freed.
	The argument being added to the list is copied into place and
	should be freed later.
