Abstract

PURPOSE:To reduce the load of a host computer and to facilitate the development of a program by connecting a personal computer between the host computer and plural terminal equipments and providing the keyboard definition of the terminal equipments and a screen data base on said personal computer. CONSTITUTION:The keyboard definition of terminal equipments 3 and a screen data base are provided on a personal computer 2. Then, the computer 2 sends the designated screen data and check information to a designated equipment 3 by a command given from a host computer 1 or the equipment 3. Then, the equipment 3 checks the input data and sends only the desired data to the computer 1. Thus, the process value of the computer 1 is reduced and a new screen is easily produced. Furthermore, it is not required to produce a program corresponding to the new screen.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a screen management system for a terminal using a personal computer.

K Summary of the Invention: A personal computer is connected between a host computer and a plurality of terminal devices, is provided with a database of keyboard definitions and screens of the terminal devices, and the personal computer manages the screen of the terminal devices and input data from the terminal devices. This is a terminal screen management method that checks data, and has the characteristics of reducing the burden on the host computer and making program development easier.

! Conventionally, terminal screen management has been performed by tabulating and checking input data directly using a host computer program without using a screen database. This has resulted in a large amount of processing by the host computer, and The disadvantage is that a number of programs are required depending on the type of program, and the number of man-hours required for the program is enormous, making program development difficult.

[Problems to be Solved by the Invention] The purpose of the present invention is to improve the above-mentioned drawbacks of the conventional device. To provide a screen management method for a terminal device that does not require creating a program compatible with various screens.

Means for Solving Problem K] In order to achieve the above object, the terminal screen management method of the present invention allows a terminal keyboard to be displayed on a personal computer connected between a host computer and a plurality of terminals. Equipped with a database of definitions and screens, the personal computer sends the specified screen information and check information to the specified terminal according to commands from the host computer or terminal, and after the terminal checks the input data, performs necessary checks. Only the data is sent to the host computer.

K Embodiment An embodiment of the present invention will be described with reference to the drawings.

A plurality of personal computers 2 are connected to a host computer 1, and a plurality of terminals 1fi3 are connected to each personal computer 2. A storage means 4 built in or connected to the personal computer 2 stores a plurality of databases of keyboard definitions and screens of the terminal 3. Each database includes check information such as input check information and display setting information for each field. As the storage means 4, IO, RAM, FD, and other known devices can be used.

The database of screens is input from the personal computer 2, and creation of new screens, modification or addition of existing screens, etc. can be performed as appropriate using the personal computer 2, as needed.

Computer 2 is host computer 1 or terminal 3
When there is a screen display command from , the designated screen data and input check information are read out from the storage means 4 and sent to the designated terminal 3 .

The terminal device 3 displays a screen based on the screen data sent from the personal computer 2, and then uses the keyboard or the terminal device 3
When data is input from an input device such as a barcode reader or magnetic card reader connected to the terminal 3, the terminal 3 checks the input data and then sends only the necessary data to the host computer 1 via the personal computer 2. Ru.

Further, when there is a print command, the terminal device 3 outputs a print signal for the display screen to the printer and prints out the form or the like.

Next, we will explain its operation.

Now, when a screen display command is sent from the host computer 1, the personal computer 2 analyzes the command, searches for the specified screen from the database in the storage means 4, and sends it to the specified terminal 3. This screen is displayed on the terminal 3, and if a response is required, the terminal 3 checks the input data and sends only the necessary data back to the host computer 1.

Even when a screen display command is sent from the terminal 3 side, the PC 2 searches for the specified screen and sends it to the terminal 813.
A similar operation is performed.

When creating a new screen (form) or modifying an existing screen, all you need to do is create or modify the screen using the personal computer 2 and store it in the storage means 4, and the program on the host computer 1 can be No need to modify.

The effectiveness of K invention! ! ! ] As explained above, the terminal screen management method of the present invention enables the terminal screen management to be performed by the personal computer by equipping the personal computer with the definition of the keyboard of the terminal and the database of the screen. The program is smaller and requires less processing on the host computer.
Additionally, a new screen can be introduced by basically adding a database using one program, making program development extremely easy.

Claims (1)

[Claims] A personal computer connected between a host computer and multiple terminals is equipped with a database of terminal keyboard definitions and screens, and the computer is designated as a designated terminal by instructions from the host computer or terminal. A terminal screen management method characterized in that data and check information are sent out, the terminal checks input data, and then only necessary data is sent to a host computer.
