	  x, y,	z, w
		   Specify x, y, z, and	w coordinates of a vertex.
		   Not all parameters are present in all forms of the
		   command.

     FORTRAN SPECIFICATION
	  SUBROUTINE fglVertex2dv( CHARACTER*8 v )
	  SUBROUTINE fglVertex2fv( CHARACTER*8 v )
	  SUBROUTINE fglVertex2iv( CHARACTER*8 v )
	  SUBROUTINE fglVertex2sv( CHARACTER*8 v )

	  SUBROUTINE fglVertex4fv( CHARACTER*8 v )
	  SUBROUTINE fglVertex4iv( CHARACTER*8 v )
	  SUBROUTINE fglVertex4sv( CHARACTER*8 v )


     PARAMETERS
	  v    Specifies a pointer to an array of two, three, or four
	       elements.  The elements of a two-element	array are x
	       and y; of a three-element array,	x, y, and z; and of a
	       four-element array, x, y, z, and	w.

     DESCRIPTION
	  fglVertex commands are used within fglBegin/fglEnd pairs to
	  specify point, line, and polygon vertices.  The current
	  color, normal, and texture coordinates are associated	with
	  the vertex when fglVertex is called.

	  When only x and y are	specified, z defaults to 0 and w
	  defaults to 1.  When x, y, and z are specified, w defaults
	  to 1.

     NOTES
	  Invoking fglVertex outside of	a fglBegin/fglEnd pair results
	  in undefined behavior.
