	status.i4.v = wn_select_field_set_by_value_c(window_id.i4.v,

			wn_view(_c))
	select_id	ID of selection field type (returned from a prior
			call to wn_select_field_register_c)

	OK			success
	CBS_NO_SUCH		select field does not exist
	CBS_NOTENB		select field is disabled or does not support
				setting by value
	CBS_INVARG		invalid entry or select ID passed
