A basic message is derived from a message database file based on an identifier indicative of the sort of an event contained in event data under control of an event message forming program. A message component specific to the event contained in the event data is derived under control of an event data acquiring procedure. The event message forming program inserts the message component into the basic message to thereby complete a desired message. When the basic messages and the event data acquiring procedures are prepared in correspondence with the new sorts of events, these new sorts of events can be simply accepted in the conventional main structure. <IMAGE> |
