Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a control method for editing, changing, etc. a display screen in a system in which a program running on a processor communicates with an operator through a display screen.

[Background of the invention]

When performing single-screen display in an information processing system, it is necessary to specify the format of the single display screen (field position on the screen, length, color, presence or absence of blinking, etc.) and information unique to the display device. However, in the past, this information was defined in the access source program (business program) and a single display screen was created, so it was necessary to modify the business program when adding or changing a single display screen or changing the display model. In addition, since the interface between the business program and the screen editing program cannot be determined regardless of the display format, when adding new display data in the business program,
It is also necessary to change the screen editing program, making it difficult to easily change or add a display screen or to display it on a different display device.

Furthermore, in JP-A No. 56-60975, when tabulating data, a file section for registering the tabulation contents in the storage device is created, tabulation is performed by referring to the contents of this file, and 1.
When it is necessary to change the tabulation, a method has been disclosed that simplifies the task of changing one tabulation item by changing the tabulation item and its position within the file, but it is difficult to change the program. It does not take into account what can be achieved without doing something.

[Purpose of the invention]

An object of the present invention is to add a display screen without changing programs such as a business program or a screen editing program in a system that performs various communications between a program running on a processor and an operator through a display screen.
The purpose of the present invention is to provide a display screen editing method that allows changes and display model changes.

[Summary of the invention]

In the present invention, screen definition information consisting of information specifying the display format of one display screen data, information regarding the display model, etc. is stored in a file, and the screen definition information can be arbitrarily added or modified from outside. The interface between the business program (screen access source program) and the screen editing program is independent of the display format 1 display model, and the screen editing program uses the screen data passed from the business program with the screen definition information on the file. Edit based on the file and output to one display device.

[Embodiments of the invention]

FIG. 1 shows the basic structure of the present invention.

In FIG. 1, the screen access program, which is a business program, is created for business purposes. Screen definition information indicating the screen display format and device type for each job is provided in the screen definition information file 12.
Store it in . In other words, when displaying on one screen, design the display screen in advance (screen configuration, display position, one color, etc.)
The results are registered in the screen definition information file 12.

The screen editing program 14 reads screen definition information corresponding to the screen data passed from the screen access program from the file 12, edits the screen based on the definition information, and displays the edited screen on the display device 13.

In this case, one piece of screen definition information is composed of, for example, the following information.

■ Transaction code: Specifies which screen the transaction data (added, changed data) corresponds to.

■ Title Define in advance the title to be displayed in the title area of the second screen.

■ Screen change when specifying the light pen area Specify the color and presence or absence of blinking when specifying the light pen area.

Specify whether there is an underground line or not.

Furthermore, there is the following definition information for fields that are displayed on the screen.

■ Field position: Define the position of the field to be set on the screen.

■ Field length: Define the field length.

■Key data: 0 pieces of key data that define the key data corresponding to the above fields are used to correlate with the display data passed from the screen access program.

■ Initial data: Define the initial data of the field.

■ Initial data control data: Initial data color.

Specify the presence or absence of blink and the presence or absence of angle line.

■ Device type: Specify the device model that displays the screen.

As shown in FIG. 2, the one-screen access program 11 and the screen editing program 14 are stored in an external storage device 22 as program files.

Similarly, the screen definition information file 12 is also stored in the external storage device 23.
is stored in. The external storage devices 22 and 23 may be the same device. At the start of business, the screen access program 11 and the screen editing program 14 are stored in the external storage device 22.
The data is loaded into the main memory 21 of the computer. Moreover, the one-screen definition information file 12 is stored in the main memory in advance before executing the one-screen editing program! 21, in this way, in addition to program 11.14,
Screen definition information file! 2 is also the main memory device i! 21, it is not necessary to access the external storage device 23 every time one screen definition information is referenced.

Next, a processing example of the method of the present invention will be explained with reference to FIG. FIG. 3 shows the processing up to displaying transaction data passed from the screen access program on the screen.

Screen access program 11 adds screens.

When a change or the like arises, a 1-display request list 31 is created without being aware of the display format 1 display model, etc., and the display is requested to the screen editing program 14.

The 2 to 1 display request list 31 includes a transaction code (xxxx in FIG. 3) indicating which definition information registered in the screen definition information file 12 corresponds to, key data (in FIG. 3) associated with the screen field. AAA
), new display data (aaa in FIG. 3), color of the display data, presence or absence of blinking, etc.

The screen editing program 14 first selects the screen definition information 32 of the corresponding transaction code (XXXX in FIG. 3) in the one-screen definition information file 12 based on the transaction code of the display request list 31 passed from the screen access program 12. 0th and 1st display request list 3
Field definition information (field address, length, etc.) corresponding to the key data (AAA) in 1 is screen definition information 3.
2, and edit the display data (a a a) into the field. At this time, if initial data (A in FIG. 3) for the corresponding key data is specified in the screen definition information 32, the initial data is the transaction data (a
a The 0 screen editing program updated by a) is
This editing result is matched to the display model (ZZ in FIG. 3) in the screen definition information 32, and the screen 33 is displayed on the display device i13.

According to this embodiment, the format of the display screen (position, one color, blink, etc.) can be changed simply by changing the contents of the screen definition information file. Furthermore, by adding a transaction code to the instruction light and screen definition information of the screen access program, one additional screen of display data can be added without changing the program. Furthermore, when outputting to a different display model, it is possible to do so by simply changing the model information in the one-screen definition information file.

FIG. 4(a) shows the processing flow of the screen access program, and FIG. 4(b) shows the processing flow of the screen editing program.
