In a storage plasma panel display, a graphic cursor in the form of a cross-hair may be displayed and moved about the screen by a joystick or under program control by selectively writing and erasing the cross-hair only in even-X and even-Y picture element (pel) addresses. The stored display data is maintained in the remaining 75% of the addressable pel positions. Thus, the cross-hair can move throughout the screen of stored data without damaging (overwriting or erasing) the basic image.
