This attribute is writeable for the browse widget only. If the LABELS attribute is set to FALSE for a browse widget, no column headers will appear with the browse.
If the LABELS attribute is FALSE for a combo-box, editor, fill-in, or text widget, no label appears with the widget. If the attribute is FALSE for a frame, the NO-LABELS option is specified in the frame phrase for the frame and no labels are displayed with field-level widgets within the frame.
