Abstract
Abstract According to the invention, when a target name is inputted using characters such as alphabet and numerics, strings of characters or numerics are compared with data of registered places each time one character is inputted, names of registered places including the inputted string of characters or numerics is listed, and the number of registered target names remaining on the list is displayed. When the target name is inputted in characters, the inputted data is compared with a list of the registered names having word components arranged in different orders with respect to a single official name by a forward match comparison, and the number of registered target names remaining on the list with forward match is displayed. When the number of the inputted characters or numerics increases and the number of registered target names remaining on the list decreases, a list of the registered place names is displayed. The target name is selected from this list. When the number registered target names remaining on the list is one, the target name is selected. A map of the vicinity of the target name thus selected is displayed.
