Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a screen control method for a general-purpose terminal device, etc. In recent years, nine types of general-purpose terminal devices have become widespread.

In many of these, fixed display screens such as forms are prepared depending on the business, and the corresponding entry fields (hereinafter referred to as fields) are prepared.
Predetermined data processing is performed by inputting and outputting data to and from the .

There are many fixed screens listed above for each job (although they will be prepared).

Screen information for controlling these screens (hereinafter referred to as screen definitions) has also become enormous, and therefore there is a demand for a simple screen control method that reduces the number of screen definitions.

[Conventional technology]

A conventional screen control method will be explained according to a flowchart showing the screen control method shown in FIG.

When creating a form, etc., an operator first specifies a form name, and a fixed screen as shown in the display section 8 of FIG. 2 is displayed. Subsequently, when the cursor is moved to a predetermined entry column (field) and data is input, the data is stored in the storage device and displayed in the field.

When data input is completed and specified manually using a key, etc., the sum of two amounts, etc. is calculated and displayed in the corresponding field.

The screen control related to the screen display is performed by the screen control program 21 with reference to the screen definition body 22 that defines the attributes of the fixed screen and fields.

The outline of its operation will be explained below.

In FIG. 2, 20 is an application program, 21 is a screen control program, and 22 is a screen definition body.

The screen control program 21 is a screen definition body 2 that defines a screen.
2, and in response to a request to display the application program 20,
A predetermined screen is displayed with reference to the screen definition body 22.

The screen definition body 22 is composed of a fixed literal table 23, a field table 25, and a field search table 24 for searching the table 25, and is prepared for every nine screens.

The fixed literal table 23 is a table that defines a fixed display screen, and to explain the case of the display example in FIG. 2, each fixed display screen has a plurality of horizontal ruled lines 101.
Vertical ruled line 1o2. It is divided into 100 fixed literals such as product names, etc., and data necessary for nine displays is stored. The data format is when the display section 8 is a character display device.

(11 Number of rows and digits indicating the display position (2) Flags specifying display attributes such as color, brightness, blinking, etc. (3) Field length indicating the size of the fixed literal (
4) Consists of display character information, etc. A table storing the above information is provided for each character (eg, vertical ruled line) or literal unit (eg, product name, etc.).

The fixed literature table 23 is defined for each screen,
It is read by the screen control program 21 and displayed by specifying the start address.

The field table 25 defines attributes of data input and output to the field.

In the display example of FIG. 2, field 1 (103).

...Data and display attributes are defined for all fields of the screen, such as field n (104).

i.e. for each field (1) Lines and digits representing the display position (21 colors, display attributes such as blink, and Japanese.

Data attributes (4) of alphanumeric characters, kana, etc. Field lengths, etc. are defined and prepared for each fixed literal table 23.

The data area 26 is a storage area for data input into the above fields, and is accessed by the application program 2° and the screen control program 21.

The 9-screen control program 21, which is the function of each of the above parts, reads the fixed literal table 23 from the top address of the fixed literal table 23 at the request of the application program 20, displays the fixed screen, and also displays the fixed literal table 23 based on the input data. After checking the data attributes etc. with reference to the field table 25, the data is stored and displayed in the corresponding data area.

Note that the field search table 24 stores pointers for each field in the field table 25 and data addresses of eight fields in the data area, and is used to search the field table 25 and field data.

[Problem that the invention seeks to solve]

As explained above, the screen definitions for defining and displaying fixed screens such as forms are prepared for each screen, so screens that differ only in the size of one screen, or screens that differ only in part of fixed literals or field attributes are possible. However, since the screen definition is prepared, it not only takes effort to create one screen definition.

There is a problem in that the capacity of the storage device that stores the screen definition increases.

[Means for Solving the Problems] The above-mentioned problems with the conventional technology include means for controlling the display screen using screen information that defines a fixed screen and entry fields, and a plurality of the above-mentioned screens stored in the first storage means. means for extracting specified screen information from the information, processing the change, and storing it in the second storage means;

1st. This problem can be solved by the screen control method of the present invention, which includes means for specifying the storage location of the second storage means and controlling the screen.

[Effect]

According to the present invention, when a certain screen definition can be used with some modification, the application program stores the screen definition in a storage means under its own management, and its contents, such as fixed literals, are stored in the storage means under its own management. Changes characters, field attributes, etc., and notifies the screen control program of the address of the screen definition. If no change is required, specify the screen definition name.

By using the above means, the single-screen control program can perform screen control using the conventional procedure.

Therefore, the troublesome task of creating a screen definition program can be reduced, and the storage capacity for storing nine screen definition programs can be reduced.
