摘要：
In a map display system, map-forming data necessary for display of a display area and character data representing display areas are stored in a map data memory. A display area commander reads map-forming data indicating a specified display area out of the map data memory, and produces a display area instruction. A display character commander selects character data for a given point of the specified display area designated by the display area designation commander, and produces a display character instruction. On the basis of the display area instruction from the display area commander and the display character instruction from the display character commander, a map of the specified display area and characters in the specified display area are displayed on a display.
