Abstract

PURPOSE:To perform the real-time display of the working state of each work program by setting the working states of work programs to a shared memory and always monitoring the information on the shared memory. CONSTITUTION:The work programs 41-44 replace directly and in real-time the state statuses 31-34 set in an inter-task shared memory 3 in response the programs 41-44 respectively. While a program working monitor program 5 always monitors the statuses 31-34 and displays the working states of the programs 41-44 on a display device 2 in accordance with the statuses 31-34 respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for displaying the operating status of a program, and more particularly to a method for displaying the operating status of a program when a plurality of programs are running in multitasking on a central processing unit.

[Conventional technology]

Conventionally, displaying the operating status of this type of program has been performed in some large central processing units, but it required intervention from the operating system and was not easy to operate.

[Problem to be solved by the invention]

With the conventional method of displaying the program operating status described above, it is not possible to display the program operating status on the screen unless the operating system has a function to manage the operating status of the program. The disadvantage is that it cannot be configured.

In view of the above-mentioned points, an object of the present invention is to display the operating status of each business program on a display device in real time by having a program operation monitoring program constantly monitor the operating status of each business program via an inter-task coexistence memory. The purpose of the present invention is to provide a method for displaying the program operating status in a manner that enables the user to display program operating status.

[Means to solve the problem]

The program operation status display method of the present invention is an information processing system that includes a central processing unit that can run multiple programs in multitask mode, and a display device that can control both sides of the display from a program running on the central processing unit. In the system, an inter-task shared memory provided in the central processing unit described in Section 11i and the operating status of a self-service program running in multitask on the central processing unit are set in real time on the inter-task shared memory as a status status. A plurality of business programs operate in multi-task mode on the central processing unit, constantly monitor the state status of each business program on the inter-task shared memory, and display the operating status of each business program on the screen on the display device. It also includes a program operation monitoring program.

[Effect]

In the program operation status display method of the present invention, an inter-task shared memory is provided in the central processing unit, and a plurality of business programs operate in multitask mode on the central processing unit, and the operation status of the own business program is used as a status status between tasks. The program operation monitoring program is set in real time on the coexisting memory, runs multitasking on the central processing 'AH, constantly monitors the status status of each business program on the intertask coexistence memory, and displays the operating status of each business program. Display both sides on the device.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an information processing system to which a program operation status display method according to an embodiment of the present invention is applied. This information processing system consists of a central processing unit 1 that can run multiple programs in multitasking, and a CRT (Cathode Ray Tube) that can control the display screen from the programs running on the central processing unit 1.
The display device 2 is configured such that it is connected to a display device 2 made up of the following.

The central processing unit 1 is provided with an inter-task shared memory 3 that can be arbitrarily referenced and updated by a plurality of programs running on the central processing unit 1.

In addition, on the central processing unit 1, a plurality of (four in the figure) business programs 41 to 44 whose operating statuses of their own business programs are set as status statuses 31 to 34 in the intertask shared memory 3, and an intertask coexistence memory A program operation monitoring program 5 that constantly monitors the status statuses 31 to 34 corresponding to each of the business programs 41 to 44 on 3 and displays the operating status of each of the business programs 41 to 44 on both sides on the display device 2.
is working with multitasking.

Next, the operation of the program operation status display method of this embodiment configured as described above will be explained.

Each of the business programs 41 to 44 running as a multitask on the central processing unit 1 stores its own business program o-:44 in the inter-task shared memory 3 according to the process currently being performed.
Corresponding state statuses 31 to 34 are directly updated in real time.

On the other hand, each business program 41 to 44 is displayed on the central processing bag Wl.
The program operation monitoring program 5, which is running simultaneously in a multi-task manner, constantly monitors the state statuses 31-34 corresponding to each business program 41-44 in the inter-task coexistence memory 3, and Each business program 41-34 corresponds to the status status 31-34.
44 is displayed on the screen on the display device 2.

The screen display on the display device 2 displays the name of the process currently being executed, or displays in reverse video the name of the process currently being executed out of a function list consisting of multiple process names of each business program 41 to 44. You can configure it as you like.

FIG. 2 is a diagram showing an example of the configuration of a display screen for the operating status of a program on the display device 2. As shown in FIG. This display screen displays in reverse video the name of the currently executing process 22 out of a function list consisting of a plurality of process names 22 corresponding to the business program name 21 of each business program 41 to 44. Yes, for example, for business program name 21 "Communication management task", "Initialization", "Idle"
, "Edit send text", "Send data", "Receive data".

A function list consisting of a plurality of process names 22 such as ``Received Text Analysis Calculation'', ``Aggregation'', and ``Return to System'' is displayed, and the process name 22 currently being executed is highlighted.

〔Effect of the invention〕

As explained above, the present invention constantly monitors the state status of the inter-task shared memory, which is updated in real time by each business program, using a program operation monitoring program, thereby monitoring the constantly changing operating status of each business program in real time. There is an effect that the screen can be displayed on a display device.

In addition, the operating status of the business program can be displayed regardless of the type or function of the operating system of the central processing unit, and the display screen can also be configured freely.For example, the first business program This has the effect of dividing the processing into arbitrary processing units and displaying them in an easy-to-understand manner according to the purpose.
