status.i4.v = wn_point(x.r4.r, y.r4.r)

	status.i4.v = wn_point_c(x.r4.v, y.r4.v)

	This routine plots a point at virtual coordinates X,Y in a graphical
	window specified by a previous call to wn_active(_c).  wn_view(_c)
	and wn_world(_c) must also be called before calling this routine.
	The color of the point is determined by the most recent call to

	x, y		real world coordinates of the point

	This function returns ACNET status values as follows:

	OK			success
	CBS_NOSETUP		an active window has not been established
	CBS_MEMFAIL		failed in allocating dynamic memory

	This function requires the following include files:

	cbslib_h, acnet_errors_h

	Related functions:

	wn_point_set, wn_view(_c), wn_world(_c), wn_active(_c), wn_color(_c),
	wn_user_defined_color_c, wn_read_user_defined_color,
	wn_connect_points(_c), wn_plot_fill(_c), wn_symbol(_c), wn_flush,

	C/C++ usage:

	int	status;
	float	x = 1.0;
	float	y = 1.0;

	status = wn_point_c(x,y);
