JPH032919A - Screen data input/output system for terminal equipment - Google Patents

Abstract

PURPOSE:To improve the availability of a memory and to reduce the working value by storing previously each field command data into a disk in the form of a screen file to have accesses to these command data as necessary via the disk and at the same time carrying out the input/output operations of screens via the accesses screen file. CONSTITUTION:A console display is prepared together with a disk and a terminal equipment. The console display can display and input the pictures. The disk stores the field command data for input/output of the console display for each screen file. Then the terminal equipment carries out a program task with an access given to the disk and performs the display/input operations to the console display. Thus the screen files stored previously in the disk are used. As a result, a memory is effectively used and the input/output of screens can be attained with no consciousness of each program task. Then the operability is improved in a screen data input/output system.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to screen display and input on a console display, and particularly to a terminal device system that has many screen display patterns and is frequently accessed.

(Prior art) Conventionally, in this type of data input/output method, field command data for all patterns were defined in the memory of each program task, so the definition section was huge and it was difficult to use the limited memory. was very inefficient.

Next, a conventional method will be explained with reference to the drawings.

FIG. 8 is a diagram showing the program configuration of the terminal device.

In FIG. 8, ■ indicates the operation of displaying on the console display using field command data for screen display on the memory of the program task. Also, ■ indicates an operation of acquiring human data from the console display using field command data for inputting screen data on the memory of the program task.

FIG. 4 is an explanatory diagram showing details of the process.

In FIG. 4, ■ indicates the operation of displaying on the console display using field command data for screen display on the memory of the program task. 3 shows the operation of acquiring input data from the console display using the screen data and manual field command data in the memory of the program task. 3 shows the operation of displaying on the console display using field command data for screen display in the memory of the program task. 3 shows the operation of acquiring input data from the console display using field command data for inputting screen data on the memory of the program task. 3 shows the operation of displaying on the console display using field command data for screen display in the memory of the program task. 3 shows the operation of acquiring input data from the console display using field command data for inputting screen data on the memory of the program task.

Therefore, field command data must be defined in the memory of each program task not only for each screen but also for each purpose, which increases the memory retention rate.

(Problems to be Solved by the Invention) The above-mentioned conventional screen data input/output method stores display field command data, input field command data, underline display field; cloak data, etc. for each program task according to the screen type. Since it is defined on the internal memory, it has the disadvantage that the usage efficiency within the limited memory is very low.

Also, when using the same screen in other program tasks, it takes K to define the same data, so the amount of work is also 2.
There is also the disadvantage that it doubles and becomes wasteful.

An object of the present invention is to store each field command data on a disk in advance in the form of a screen file, access it from the disk whenever necessary, and perform screen input/output operations using the accessed screen file. It is an object of the present invention to provide a screen data input/output method for a terminal device configured to eliminate the above drawbacks, improve memory usage efficiency, and reduce the amount of work.

<ll! Means for Solving the Problem) A screen data input/output method for a terminal device according to the present invention is configured to include a console display, a disk, and a terminal device.

A console display is a book that allows you to display/enter images.

The disk is for storing field command data for display/input on the console display in units of screen files.

The terminal device is for executing program tasks and displaying/inputting on a console display by accessing the disk.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a screen data input/output method of a terminal device according to the present invention.

In the diagram alE1, the screen file is acquired from the disk by ``■'', and the field command data for screen display of the screen file read into an area of the program task is displayed on the console display by ``■''. Next, by using the field command data for inputting screen data of the screen file, input data is obtained from the console display.

FIG. 2 is an explanatory diagram showing details of processing in the apparatus shown in FIG. 1.

In FIG. 2, the screen file is acquired from the disk in step 1, and field command data for screen display of the screen file read into an area of the program task is displayed on the console display in step 2. Next, ■
Obtain input data from the console display using the screen data input field command data of the screen file. Furthermore, the screen file is obtained from the disk using ■.

In (2), field command data for screen display of the read screen file in area (common) K of the program task is displayed on the console display. Next, in step (3), input data is obtained from the console display using the screen data input field command data of the screen file.

In addition, ■ Get the screen file from disk. Next, in (2), field command data for screen display of the read screen file in area (common) K of the program task is displayed on the console display. Next, in step (3), input data is obtained from the console display using the screen data input field command data of the screen file.

Therefore, since all the data is already stored on the disk as screen files, each program task only needs to reserve one area for reading the screen file, and it can be used freely and without being aware of the program task. Screen files can be obtained. Therefore, memory can be used effectively.

(Effects of the Invention) As explained above, the present invention makes it possible to use memory effectively by using a screen file that is stored in advance on a disk, and also allows the screen to be displayed without being conscious of each program task. This has the effect of improving operability because input and output can be performed.
