status.i4.v = wn_view_construct_c(window_id.i4.r, x.r4.v, y.r4.v,
					  y_coord_type.i4.v, width.r4.v,

	This routine creates and sets the screen limits (virtual coordinates)
	for a graphics window whose ID is returned in "window_id".  The values
	("x", "y", "width", "height") are in fraction of screen units
	and should be between 0.0 and 1.0 inclusive.

	window_id	returned window ID
	x		X coordinate of left border of window
	y		Y coordinate of either the top or the bottom
			of the window depending on "y_coord_type"
	y_coord_type	type of Y coordinate in the previous argument
			(CLIB_DEFAULT_ARG -> Y coordinate of the bottom
					     of the window,
			 WN_BOTTOM_COORD -> Y coordinate of the bottom
					    of the window,
			 WN_TOP_COORD -> Y coordinate of the top
					 of the window)
	width		width of the window
	height		height of the window

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVARG		invalid coordinates specified
	CBS_MEMFAIL		failed in allocating dynamic memory

	This function requires the following include files:

	cbslib_h, acnet_errors_h

	C/C++ usage:

	int	status;
	int	window_id;
	int	y_coord_type = WN_BOTTOM_COORD;
	float	x = 0.1;
	float	y = 0.1;
	float	width = 0.8;
	float	height = 0.8;

	status = wn_view_construct_c(&window_id,x,y,y_coord_type,
