Description

[Detailed description of the invention] [Table of contents] Overview Industrial application field Prior art (Figure 5) Problems to be solved by the invention Means for solving the problems (Figure 1) Effects Examples (Figure 1) (Figures 2 to 4) Effects of the Invention [Summary] When performing screen processing using screen definitions, common parts of the screen definitions are segmented in advance and stored in files, and the screen definitions are divided into sections before execution of the screen processing. At times, common screen definitions are read out from files and combined to reconstruct the screen definitions necessary for business operations.

[Industrial application field]

The present invention relates to a screen definition file processing method, and in particular, the screen definition file is divided into display units and filed for each division, and when performing screen processing on a display terminal, necessary divisions are read out from the file and concatenated. A screen definition is created, and data is input based on the screen definition thus obtained.

[Conventional technology]

In a terminal device, a screen definition is displayed on a display, data is input into fields designated on the screen definition, and necessary information is inputted.

In this case, a screen definition is prepared for each job, and the required screen definition is read from the file and output on the display.

For example, when a bank employee performs a deposit operation in a financial business, the screen definition is a three-page definition for the customer, input method, and amount, as shown in Figure 5a.
It is composed of a ₁ , a ₂ , a ₃ , and the screen definition when performing withdrawal operations is composed of two pages of definitions b ₁ and b ₂ for customer and amount, as shown in b. There is.

Each of these screen definition bodies is held in a file for each terminal for each task.

[Problem that the invention seeks to solve]

By the way, as described above, conventionally, screen definition bodies are individually maintained for each task. Therefore, as mentioned above, in the deposit screen definition, three pages of definitions a ₁ , a ₂ , and a ₃ for customer, deposit method, and denomination are held together in a file, and for withdrawal In the screen definition body, definition bodies b ₁ and b ₂ of two pages, ie, customer and denomination, are combined and held in a file.

Therefore, even if some of the pages are the same, such as b ₁ = a ₁ , b ₂ =, a ₃ , a screen definition is maintained for each job, so the amount of definitions becomes large. There is a problem.

In addition, if the page division as shown in Figure 5a is
Store a ₁ , a ₂ , a ₃ separately in a file,
If you want to read out a ₁ and a ₃ separately and output the screen definition for withdrawal to the display as shown in Figure 5b, first open the screen and read the definition of the page classification for the customer. After displaying the screen, the screen is closed once, and the screen is opened again to read the definition of the page classification for the denomination.
There is a problem that the processing speed becomes slow.

The purpose of the present invention is to solve such problems by not only reducing the file size, but also by changing the screen at the switching part between the page divisions of the screen definition program when reading out a screen definition file with multiple page divisions. It is an object of the present invention to provide a screen definition program processing method that does not include open and close processing.

[Means for solving problems]

In order to achieve the above object, the screen definition processing method of the present invention provides a screen definition of a data processing device that displays a screen definition on a display unit and inputs and outputs data to an input/output area provided in the screen definition. In the system processing method, a screen definition is assigned a screen number to each screen definition that has a screen format used for a business and a screen definition that is a screen format that is common across multiple businesses, and the screen definition used for each business is created. A screen number table is provided on the center host side that holds the screen number of the system and instructions for use of the input/output area provided in the screen definition in the relevant business in correspondence with the business name, and the definition of the numbered screen definition is provided on the center host side. A terminal includes a file that holds information, a definition processing unit that reads a screen definition from the file based on the screen number, and a screen processing unit that outputs the screen definition obtained from the definition processing unit to a display unit. When carrying out a job, the computer notifies the host of the job name from the terminal, receives the screen number that constitutes the screen definition for the job from the screen number table, and reads the screen definition from the file based on this. When displaying on the display, if multiple screen numbers are specified, the multiple screen definitions are displayed in a concatenated manner, and input/output to unused input/output areas is prohibited to create screen definitions that are compatible with business operations. It is characterized by having a similar structure to its body.

[Effect]

It can be seen that the screen definition for job N is composed of sections a ₁ and a ₃ , so when reading the screen definition for job N, sections a ₁ and a ₃ are successively read from the file. Also, since it can be seen that job C can be obtained by concatenating the screen definitions of jobs A and B, job C
When obtaining the screen definitions for jobs A and B, the screen definitions for jobs A and B are read out successively from the file. The file size can be reduced, and even when the display screen is switched, the screen can be closed or closed for the switching screen.
No open processing is performed.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 2 to 4.

FIG. 2 is a configuration diagram of an embodiment of the present invention, FIG. 3 is an explanatory diagram of data transmission status between a terminal and a host,
FIG. 4 is a flow chart for explaining the operation of the present invention.

In FIG. 2, 1 is a terminal device, 2 is a file such as a disk file, 3 is a keyboard,
4 is a display section, 5 is a processor (CPU), 6 is a main memory, 7 is a screen processing section, 8 is a definition program processing section, 10 is a host processor, and 11 is a screen number table.

File 2 is connected to terminal device 1,
The screen definitions for each business or the divided screens (for example, page unit screens) constituting the screen definitions are stored, and application programs are stored therein.

The host processor 10 is provided at the center, and when a business name is transmitted from the terminal device 1, it stores the screen number and fields to be used necessary to configure a screen definition corresponding to the business name. The screen number table 11 that is currently available is searched and the required screen number is returned.

The screen number table 11 is a table in which screen numbers for obtaining screen definitions necessary for a business are entered in correspondence with business names.

Now, as shown in Figure 3a, task A is screen number
Using the screen definition of RQ1, job B has the screen number
Using the screen definition of RQ2, job C has the screen number
When a screen definition program in which RQ1 and RQ2 are connected is used, if the terminal device 1 makes an inquiry to the center's host processor 10 about the screen definition program with business name A, the field used in screen number RQ1 is A. ₁ , A ₂ , and A ₃ by searching the screen number table 11 and sending this back to the terminal device 1 . Similarly, if the terminal device 1 inquires about the screen definition with business name B, the host processor 10 informs the terminal device 1 that the screen number is RQ2 and that the fields to be used are B ₁ and B ₂ .
Reply to.

By the way, if there is an inquiry from the terminal device 1 for the screen definition of task C, the host processor 10 searches the screen number table 11 and selects the screen number RQ1.
It reads that the concatenated RQ2 is the screen definition for business C, but field _A3 of screen number RQ1 is not used, and returns this. At this time, information on fields that are valid when screen number RQ1 is used in task C is stored in advance in the screen number table. Actually, when job C is selected from the terminal device, the host refers to the screen number table and returns the necessary screen number and field information.

Also, as shown in Figure 3b, if there is an inquiry about the screen definition of job D, screen numbers RQ5, RQ6,
It is returned that the fields E ₁ , E ₂ , F ₁ , F ₂ , G ₁ to _{G 3} of RQ7 are used. In response to the query for the screen definition for job H, the screen definition is a concatenation of screen numbers RQ5 and RQ7, and its fields E ₁ , E ₂ ,
Reply that G ₁ to G ₃ are used.

When these screen numbers and fields are returned, the terminal device 1 reads the screen data for the screen number from the disk file 2, and if there are fields that are not used, for example, for field A ₃ in job C, Display a sign indicating that the item is not to be used.

The user only has to input data into the necessary fields of the screen definition displayed on the display section 4 in this way.

Next, the operation of the present invention will be described based on a flowchart for explaining the operation shown in FIG. 4, for a case where data for job A is first input, and then data for job C is input. Note that ~ below corresponds to the chart on the left.

In Fig. 4, the left side is mainly the definition field processing section 8.
The right side mainly shows the operation of the screen processing section 7.

For example, when the operator inputs this information from the keyboard 3 to perform task A, the terminal device 1 inputs this information to the host processor 1 of the center.
Notify 0. The host processor 10 accesses the screen number table 11 and returns the screen number RQ1 of the screen definition for business A and the field names A ₁ , A ₂ , A ₃ to be used to the terminal device 1 . With this screen number RQ1, the definition program processing unit 8
is read from file 2 and loaded into main memory 6.

The definition program processing unit 8 generates a screen definition program in the main memory 6.
Make an open request to the screen processing program using RQ1 and the work area as parameters. As a result, the screen processing section 7, which had been in a processing request waiting state, stores the information of the first screen definition in the work area. If the operator inputs open,
This open request is transmitted to the hardware,
This screen definition is displayed on the display section 4.

The operator can use fields A ₁ to _{A 3} on this screen.
Enter the required data. Then, when a read instruction is given, the screen processing section 7 inputs these fields.
Read out the data entered in A ₁ to _{A 3} .

When the operator instructs the storage of this data, these read data are written into the data storage portion of the main memory 6.

When the operator inputs task C from the keyboard 3, for example, without closing the screen after completing the processing for task A through the operations described above, the terminal device 1 notifies the host processor 10 of this. The host processor 10 accesses the screen number table 11, and the screen definition for job C is screen number RQ.
1 and RQ2, and the fields A ₁ , A ₂ , B ₁ , and B ₂ to be used are returned. As a result, the definition program processing unit 8 recognizes that the screen with the screen number RQ1 is currently being output to the display unit 4, so it reads the screen number RQ2 from the file 2 and loads it into the main memory 6. .

The definition program processing unit 8 uses the screen definition program RQ2 in the main memory 6 and the work area specified for the first open as parameters, and requests the screen processing program to continue open processing with a note that it is not used in field A ₃ . do. As a result, the screen processing unit 7 stores the continued screen definition information in the work area, and the screen definition of RQ2 is displayed on the display unit 4 in conjunction with the screen definition of RQ1 that has been displayed so far. . However, the field
A ₃ is displayed as unused.

The operator selects field A ₁ on this new screen,
Enter the necessary data in A ₂ , B ₁ , and B ₂ . When a read instruction is issued, the screen processing section 7 reads out the data input into these fields A ₁ , A ₂ , B ₁ , and B ₂ .

When the operator instructs storage of this data, these read data will be stored.

After inputting the necessary data in this manner, the operator performs screen closing processing, but this need only be done for the first screen definition, that is, RQ1.

〔Effect of the invention〕

According to the present invention, it is possible not only to reduce the number of screen definition files but also to reduce their storage amount, thereby not only reducing the file capacity, but also making it possible to reduce the size of the screen for the switching screen even when the display screen is switched. Since there is no need to perform close and open processing, processing speed can be increased. Moreover, on the terminal side, just by making an inquiry about the job, the host side will notify the screen number and necessary fields required for that job, so the terminal side will read these notified fields from the file. Since there is no need to input an address for reading a field from a file on the terminal side, the burden on the user on the terminal side can be reduced and data processing can be performed quickly.
