On the screen of a display device (MO), an operating object (BO1, BO2...) displaying a value in analog manner is displayed. After setting a cursor to a sensitive zone of the operating object, this zone can be shifted by shifting the cursor, during which process the display changes in the same manner. The new display is detected and a value corresponding to the new display is output, possibly after conversion. The invention is applied in process automation. <IMAGE> |
