status.i4.v = wn_connect_points(on_off.i4.r)

	status.i4.v = wn_connect_points_c(on_off.i4.v)

	Sets the state of connecting points, or symbols, for the active window. 
	This will control if vectors are drawn between data plotted with 
	wn_point(_c) or wn_symbol(_c).  A previous call to wn_active(_c)
	is required.

	on_off		connection flag
			(TRUE -> connect points,
			 FALSE -> do not connect points,
			 CLIB_DEFAULT_ARG -> simply return the present
					     connection state)

	This function returns ACNET status values as follows:

	CBS_INVARG		invalid state specified
	CBS_NOSETUP		an active window has not been established
	otherwise		previous connection state

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h

	Related functions:

	wn_plot_fill(_c), wn_point(_c), wn_symbol(_c), wn_color(_c),
	wn_user_defined_color_c, wn_read_user_defined_color,

	C/C++ usage:

	int	status;
	int	on_off = TRUE;

	status = wn_connect_points_c(on_off);
