Notes


      Notes: this utility is useful for displaying varying
        text such as a status update and so on. It is designed
        to be positioned somewhere out of the way by the user
        It is initialized to display some specified lines of text
        and one or more lines are requested as reserved. The
        widget IDs of the requested reserved lines are returned
        and are used to update the corresponding lines. When
        this widget is no longer needed it may be destroyed.
        Use widget_control to update a line:
          widget_control,nid(2),set_val='New value'
        To delete do: widget_control,wid,/destroy
