<p>PURPOSE:To simplify the logic of a message output request subject by so secur ing a constitution that the message output request subject collects the informa tion in the order set by its own convenience and giving these collected informa tion to a message editing subject in sequence. CONSTITUTION:A message output request subject 3 sends a message part identifier (a) corresponding to each message part to a message editing subject 1 with a message store instruction 7. In this case, the header message parts (b), (f) and (g) are first sent. Then a traffic accident information file 13 is retrieved and the relevant information is sent as the part (f) every time an accident is detected. Finally the number of accidents, the number of deaths, and the number of wounded persons are totalized, and the message parts (c), (d) and (e) are successively sent. The subject 1 stores the contents of those received message parts (b) - (h), the identifiers (a) of each message part, and the sending order of the message parts. Thus the logic of the subject 1 is simplified.</p> |
