Abstract

PURPOSE:To take out and process only an event which occurs last and shorten the processing time by providing a specific area wherein only one event is stored, and taking the overwritten event out of the specific area, and determining and displaying the display message corresponding to the event. CONSTITUTION:When an event to an event reception part 16 occurs at an event transmission part 11, the transmission part 11 sends a request to stores the event to an event control part 12, which stores the event in an event storage part 14 by using an event storage control part 13. At a request to take the event out, the control part 12 takes the specified event out of the event storage part 14 by using an event take-out control part 15 and passes it to the reception part 16. The reception part 16 analyzes the passed event and determines the display message corresponding to the event and a terminal control part 17 which is requested to display the message displays the display message on a color display 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an event management system for a program operating on a computer system, and more particularly to an event management system between tasks.

[0002]

2. Description of the Related Art As a conventional inter-task event management method for a program operating on a computer system, an event is stored in the order of occurrence and the event is extracted in the order of occurrence, or a priority order is set and each priority order is set. The method of storing the events in the order of occurrence and extracting the events in the order of occurrence is adopted.

[0003]

The inter-task event management method in the conventional computer system as described above is often adopted in a computer system executing a large number of tasks. If you want to display a message at a specific position, and when the number of stored events is large, retrieve all the events that occurred in the past, even when displaying the same message or when only the last event occurred. Since it has to be processed in a long time, it has a drawback that the processing time is long.

An object of the present invention is to provide an inter-task event management system capable of shortening the processing time by making it possible to extract and process only the event that occurred last.

[0005]

An event management system of the present invention is an event management system for managing an execution event of a processing task in a computer system.
Provide a specific area to store only one event, store the newly generated event by overwriting the specific area,
Displaying a message regarding an event includes extracting the overwritten event from the specific area and determining and displaying a display message corresponding to the event.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a flow chart showing an embodiment of the present invention, and FIG. 2 is a block diagram showing an example of a terminal device of a computer system to which the embodiment of FIG. 1 is applied.

In FIG. 2, the terminal device 10 controls an event transmitting section 11 for transmitting an event, an event storing section 14 for storing the event, and an event storing operation and an event extracting operation for the event storing section 14. An event control unit 12 and an event reception unit 16 that processes each event to determine a message to be displayed.
And a terminal control unit 17 that includes the event control unit 12 to control the overall operation of the terminal device 10, and a color display 18 that displays a message. It has an event storage control unit 13 for controlling, and an event extraction control unit 15 for controlling the event extraction operation.

Next, the operation when one embodiment of the present invention is applied to the terminal device of FIG. 2 will be described with reference to FIG.

When an event for the event receiving unit 16 occurs in the event transmitting unit 11, the event transmitting unit 11 sends an event storage request to the event control unit 12 (step 21), and the event control unit 12 controls the event storage control. The event is stored in the event storage unit 14 using the unit 13 (step 22). After this, the event control unit 12 enters a request waiting state, and when an event storage request is received from the event transmission unit 11, the above operation is repeated (step 23). When the event transmission unit 11 sends an event retrieval request to the event control unit 12 (step 24), the event control unit 12 retrieves the specified event from the event storage unit 14 using the event retrieval control unit 15, It is passed to the event receiving unit 16 (step 25). The event receiving unit 16 analyzes the event passed from the event control unit 12 and determines a display message corresponding to the event (step 2
6) A display request is issued to the terminal control unit 17 (step 27). The terminal control unit 17, which has received the display request, displays the display message on the color display 18 (step 28).

In this way, in a system in which a plurality of events occur, when one event occurs and the previously occurring event becomes invalid, only the last occurring event is stored. By doing so, the target event can be extracted by one event extraction operation.

[0012]

As described above, in the event management system of the present invention, in the event management system in the computer system, one specific area for storing the event is provided, and the generated event is overwritten and stored in the specific area. , When displaying a message on the display device,
By managing to take out the overwritten event from the specific area and determine the display message corresponding to the event, if one event invalidates the previously generated event, 1
There is an effect that it is possible to take out the event that occurred last by the event taking-out operation of the number of times, so that it is possible to shorten the processing time.
