Abstract

PURPOSE:To perform the control of a display picture simultaneously as performing communication processing in real time and to enable data to be inputted from a keyboard. CONSTITUTION:Since a computer system 1 is provided with an operating system 3 with a function to be connected to another computer system 2, a user program 4 which performs the transmission/reception of the data between the computer system 2 via the operating system 3, a user program 5 which receives an identification code attached on every display picture data in advance and performs every kind of control for the display picture, a display picture data storage file 6 in which the display picture data is stored, a display device 7 on which the display picture data is displayed, and the keyboard 8 from which the data can be inputted, it is possible to execute another processing different from picture display processing such as the communication processing, between another computer system until required input data C can be obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display screen data control system, and more particularly to a display screen data control system for a computer system.

[0002]

2. Description of the Related Art In the conventional display screen data control method, when a program of a computer system displays a general screen, prompts an operator to input data, and fetches data from a keyboard, these input / output commands are executed. Then, this program is in a waiting state, and does not execute any other processing until the operator notifies the operator that the input / output from the keyboard is completed.

[0003]

In the conventional display screen data control method described above, when the program of the computer system displays a general screen, prompts the operator to input, and takes in the data from the keyboard, Until the operating system notifies you that the input / output from the keyboard has been completed, no other processing is executed. Therefore, apparently one program uses the communication line at the same time as input / output of the screen. In order to send and receive the data, the data that the sender sends asynchronously is temporarily stored by the operating system, and after the screen input / output of the program is completed, the receive command is executed to acquire the data and perform the processing. Therefore, there is a problem that communication processing cannot be performed in real time.
Further, when the programs for the screen input / output and the communication processing are separated, the data shared by each other needs to be exchanged by a file or the like, the interface between the programs becomes complicated, and the productivity of the program development decreases. There is also.

It is an object of the present invention to provide a display screen data control system for a computer system which controls a display screen at the same time while performing communication processing in real time and enables data input from a keyboard.

[0005]

The display screen data control method of the present invention is assigned to each display screen data in advance from a first user program that transmits / receives data to / from another computer system in a computer system. Receiving an identification code, reading the display screen data from a display screen data storage file storing the display screen data in accordance with the identification code, inputting the read display screen data to a display device, and displaying the display screen data. And a second user program for receiving input data from the keyboard and sending the input data to the first user program.

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

FIG. 1 is a block diagram of an embodiment of the present invention.

The computer system 1 has an operating system 3 having a function of connecting to another computer system 2, a user program 4 for transmitting / receiving data to / from the computer system 2 via the operating system 3, and a display from the user program 4 in advance. A user program 5 that receives an identification code assigned to each screen data and performs various controls related to the display screen; a display screen data storage file 6 that stores the display screen data;
A display device 7 for displaying display screen data and a keyboard 8 for inputting data are provided.

Next, the operation will be described.

The user program 4 outputs a predetermined identification code A to the user program 5 when it detects a state requiring data input from an operator during execution of communication processing. The user program 5 uses the identification code A
, The display screen data B is read from the display screen data storage file 6 in which the display screen data corresponding to the identification code A is stored, and the operating system 3
The read display screen data B is input to the display device 7 via the display and displayed. The operator who sees this display inputs necessary data from the keyboard 8. The user program 5 receives the input data C from the keyboard 8 via the operating system 3 and sends the input data C to the user program 4. In this way, the user program 4 can obtain the necessary input data C, but until the acquisition, the user program 4 is different from the screen display process such as the communication process with the other computer system 2. Processing can be performed.

[0011]

As described above, according to the present invention, the identification code given in advance for each display screen data from the first user program for transmitting / receiving data to / from another computer system in the computer system. Received
The display screen data is read from the display screen data storage file storing the display screen data according to the identification code, the read display screen data is input to the display device and displayed, and the input data from the keyboard is read. By including a second user program that receives and sends this input data to the first user program,
There is an effect that the display screen can be controlled at the same time while performing communication processing in real time, and data can be input from the keyboard.
