Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal local screen management method, and particularly to a terminal local screen management method in a screen type terminal used in a large-scale online data registration/inquiry system.

[Conventional technology]

Screens displayed on the screen display section of screen-type terminals (business screens for large-scale online data registration/inquiry systems, etc.)
There are two ways to manage and control screen data: one is to manage it on a host computer, and the other is to manage it as local screen data in a local screen file (screen storage unit) of a screen-type terminal (terminal local screen management method).

Compared to a method in which the host computer manages the screen, the terminal local screen management method saves the host computer's screen by storing and managing the screen displayed on the screen display section of the screen-type terminal as local screen data in a local screen file. This has the advantage of reducing the processing load, reducing the network line usage rate, and increasing the screen display speed.

Conventionally, in this type of terminal local screen management system, local screen data has been managed in a fixed length format in a local screen file.

[Problem to be solved by the invention]

In the conventional terminal local screen management method described above, local screen data is managed in a fixed length format, so as the number of managed screens (local screen data) increases, the capacity of the local screen file (screen type) increases. The disadvantage is that the area (area for managing the screen on the terminal) becomes larger.

In view of the above points, an object of the present invention is to provide a terminal local screen management method that can reduce the capacity of a local screen file by managing local screen data in a local screen file of a screen type terminal in a variable length format. Our goal is to provide the following.

[Means to solve the problem]

The terminal local screen management method of the present invention includes a screen writing control section that stores local screen data in a variable length format in a screen storage section based on a local screen writing request from a host computer; a screen readout control unit that reads variable length format local screen data stored in the screen readout control unit; a screen display unit that visually displays the local screen data read out by the screen readout control unit as a screen; An input section for inputting a screen number for instructing reading of screen data and visual display of the screen on the screen display section, and an input section for managing local screen data stored in the screen storage section in a variable length format. and a screen common control section that commonly controls the screen writing control section and the screen reading control section.

[Effect]

In the terminal local screen management method of the present invention, the screen writing control section stores local screen data in a variable length format in the screen storage section based on a local screen writing request from the host computer, and the screen reading control section stores the local screen data in a variable length format based on the local screen writing request from the host computer. The local screen data in the variable length format stored in the screen storage unit is read out, the screen display unit visually displays the local screen data read out by the screen readout control unit as a screen, and the human resources department displays the local screen data by the screen readout control unit. The screen common control unit manages the local screen data stored in the screen storage unit in a variable length format by inputting the screen number to instruct data reading and visual display of the screen on the screen display unit. The screen writing control section and the screen reading control section are commonly controlled.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the terminal local screen management method of the present invention.
Based on the screen read request from TC (Termina
l Controllier) 10, the local screen data read by the screen readout control unit 3 in the host computer is superimposed with the output data sent from the host computer, or by instructions from the terminal operator. A screen display section 5 that visually displays a screen based on the local screen data read out by the screen reading control section 3 (irrelevantly), and a PF (Program Function) corresponding to each local screen data.
on) key (not shown) is pressed to display a screen (command to display a screen based on specific local screen data).

An input unit for commanding screen display by directly inputting a screen number and inputting input data for the screen displayed on the screen display unit 5 (these commands and inputs are performed by the terminal operator). It is configured to include a certain keyboard 6 and a TCIO (screen display section 5.
A screen-type terminal is configured by the keyboard 6, TCIO, etc.).

The TCIO classifies the local screen data by screen number (identification information of the screen displayed on the screen display section 5, that is, the local screen data) based on the local screen write request from the host computer, and converts the local screen data into a variable length format. Screen storage section (local screen file) 2
a screen writing control unit 1 that stores local screen data classified by screen number in a variable length format (the screen storage unit 2 in FIG.
．． A2. When the local screen data of Bl and B2 is stored (rAlj etc. are not the screen numbers mentioned above)), the screen storage unit 2 is stored based on instructions from the terminal operator, etc.
A screen succession control unit 3 reads predetermined local screen data from the host computer and sends this local screen data to the screen display unit 5, and a local screen write request from the host computer and an instruction to display a screen to the screen display unit 5, etc. is transmitted to the screen writing control unit 1, screen reading control unit 3, etc. (including the screen display unit 5), and control regarding local screen data in TCIO (in order to manage local screen data in the screen storage unit 2 in variable length format). It is configured to include a screen common control section 4 that manages the overall control (such as control commonly performed for the screen writing control section 1 and screen reading control section 3).

Referring to FIG. 2, the data stored in the screen storage section 2 includes an index section 21 for searching local screen data based on the screen number, and a number corresponding to the screen displayed on the screen display section 5. and a screen data section 22 having variable-length local screen data.

The local screen data in the screen data section 22 is configured using one or more fixed-length storage units (screen number records) based on the data length of the local screen data. It is possible to manage the local screen data using the variable length format. However, the management of local screen data using the variable length format is not limited to C.).

Next, the operation of the terminal local screen management system of this embodiment configured as described above will be explained.

First, storage of local screen data in the screen storage unit 2 in the TCIO according to an instruction from the host computer (local screen write request) is performed by the screen writing control unit 1 under the control of the screen common control unit 4 in the TCIO. The operation in this case will be explained.

In this case, the location where the local screen data should be written to the screen data section 22 in the screen storage section 2 using the screen number of the screen related to the local screen write request as a key (in the case of storing to change existing local screen data, the location where the local screen data should be written is , and when storing new local screen data, it is a predetermined position based on the order of screen numbers) is searched by the screen writing control unit 1 with reference to the index unit 21 in the screen storage unit 2, and the search The local screen data is stored at the location in the screen data section 22 where the new local screen data is stored (when storing new local screen data, a key based on the screen number is registered in the index section 21).

In this storage, each storage unit constituting the local screen data is managed with a fixed length, and a plurality of storage units (sometimes a single storage unit) are used based on the data length of the local screen data. Local screen data in the write control unit 1 is managed in a variable length format (a plurality of storage units are linked using keys based on screen numbers). As a result, local screen data having a short data length requires only a storage area for one storage unit, and the area for managing screens on the screen terminal can be reduced.

Next, an explanation will be given of the operation when a screen (a screen before input data is input) is displayed on the screen display unit 5 in accordance with an instruction from the terminal operator's keyboard 6 of the screen type terminal.

In this case, after a screen call key (not shown) on the keyboard 6 is pressed, a screen number consisting of 4 digit alphanumeric characters (not limited to 4 digits) is input, and an execution key (not shown) is pressed. is pressed by the terminal operator (it is also possible to specify the screen (local screen data) by pressing the PF key instead of inputting the screen number consisting of 4 digit alphanumeric characters).

As a result, the local screen data corresponding to the above-mentioned screen number in the data in the screen storage unit 2 is read out by the screen reading control unit 3 (under the control of the screen common control unit 4) in the TCIO (the corresponding local screen When data is divided into multiple storage units, the multiple storage units are concatenated and read out and displayed on the screen display section 5)
.

Finally, the operation when a screen is displayed after input data is input (keyed in) from the keyboard 6 on the screen displayed on the screen display unit 5 by the terminal operator will be described.

In this case, after the input data is keyed in from the keyboard 6, the execution key on the keyboard 6 is pressed, and the keyed-in input data is transmitted to the host computer and processed within the host computer (predetermined data based on the input data). search and generation of output data).

The output data obtained through this process and the screen number of the screen on which the output data should be displayed are transmitted from the host computer to the screen terminal.

Based on the control of the screen common control unit 4 in the TCIO of the screen type terminal, the screen reading control unit 3 reads the local screen data corresponding to the above-mentioned screen number transmitted from the host computer from the screen storage unit 2. (When the relevant local screen data is divided into multiple storage units, it is read out in a concatenated manner), and is superimposed on the output data sent from the host computer and visually displayed as one screen on the screen display unit 5. .

In addition, in this embodiment, as shown in FIG.
and the case where the screen common control section 4 is arranged, but the screen writing control section 11 screen storage section 21 screen succession control section 3 and the screen common control section are installed in the screen display section 5 and the keyboard 6 without providing TCIO. It goes without saying that it is possible to realize the present invention by connecting the parts 4.

〔Effect of the invention〕

As explained above, the present invention manages local screen data in a variable length when the screen displayed on the screen display section of a screen terminal is stored and managed as local screen data in a local screen file (screen storage section). This has the effect of reducing the capacity of the local screen file (the area for managing the screen on the screen terminal).
