status.i4.v = wn_data_set_cut_c(xmin.r4.v, xmax.r4.v,
					ymin.r4.v, ymax.r4.v)

	This routine sets the minimum and maximum values to operated
	on by other routines to manipulate the saved data set for the
	active graphic window.

	xmin		minimum x value
	xmax		maximum x value
	ymin		minimum y value
	ymax		maximum y value

	This function returns ACNET status values as follows:

	OK			success
	CBS_NOSETUP		an active window has not been established

	This function requires the following include files:

	cbslib_h, acnet_errors_h

	C/C++ usage:

	int	status;
	float	xmin = 1.0;
	float	xmax = 10.0;
	float	ymin = 1.0;
	float	ymax = 10.0;

	status = wn_data_set_cut_c(xmin,xmax,ymin,ymax);
