Abstract

PURPOSE:To attain the display of several screens based on the data received from a host at one time by analyzing and editing the data received from the host and displaying the data on a display screen after allocating an ID showing the storing place of each data. CONSTITUTION:A communication controller 11 is provided together with a display data analyzing part 12 which allocates an ID to each data received from a host to show the storing places of the data after analyzing and editing them and then displays the ID in a specific area set previously on a screen 3, a display executing part 3 which displays the analyzed data on the screen 3, an input executing part 15 which inputs the ID through an input device of a keyboard 2, and an input data editing part 14 which edits the data shown by the input ID. In such a constitution, the data received from a host are edited for each screen and divided with an ID given for each screen. Thus plural screens can be controlled and therefore the data on plural screens can be received with a single data transmission request given to the host.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a screen control device that controls a display screen.

[Conventional technology]

Conventional screen control devices are executed by control statements for one screen, and when displaying data on the screen, the necessary data indicated by the control statement is received from the host, edited into a specified format, and then displayed by the control statement. Data is set at the position. In addition, the data sent from the host at a time is for one screen, and in order to display several screens, a data transfer request is sent to the host each time the screen is changed, and data is received from the host. ing.

[Problem to be solved by the invention]

In the conventional screen control device described above, the data sent from the host at a time is for one screen at a time, and in order to display several screens, a data transfer request is issued to the host each time the screen is changed. It requires a series of operations to receive data, and has the disadvantage that the screen switching speed is slow.

[Means to solve the problem]

The screen control device of the present invention includes a communication control device that controls data communication with a host, and an ID that indicates a storage location for each of the data after analyzing and editing the data received from the host.
a display data analysis unit that allocates the ID and displays the ID at a preset specific location on the display screen; a display execution unit that displays the analyzed data on the display screen; and an input execution unit that inputs the ID using an input device. and an input data editing section that edits the data indicated by the above.

〔Example〕

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

FIG. 1 is a block diagram showing one embodiment of the present invention, and FIG. 2 is a diagram showing an example of the operation flow of this embodiment.

In FIG. 1, the screen control device W1 of this embodiment is a communication control device l! that controls data communication with the host. ! 11 and
After analyzing and editing the data received from the host, a display data analysis unit 12 assigns an ID indicating the storage location to each data and displays the JD at a preset specific location on the screen 3, and displays the analyzed data on the screen 3. It includes a display execution section 3, an input execution section 15 that inputs an ID using the input device of the keyboard 2, and an input data editing section 14 that edits the data indicated by the input.

Next, the operation of this embodiment will be explained using FIG. 1 and FIG. 2 together.

First, the screen control device 1 issues a data transfer request to the host to stop and transmit highly necessary data (Sl).
. All data sent from the host is received via the communication control unit 11 (52), analyzed by the display data analysis unit 12,
It is edited for each screen, and a line indicating the storage position is added (S3).

The display data analysis unit 12 displays the rD assigned to each data via the display execution unit 13 at a preset specific location on the screen 3 (S4).

When an ID is input from the keyboard 2 via the input execution unit 15 (S5), the input data editing unit 14 refers to the input ID and displays the data stored at the position indicated by the ID. It is displayed on the screen 3 via the execution unit 14.

〔Effect of the invention〕

As explained above, the present invention controls multiple screens by editing the data received by the host on a screen-by-screen basis and assigning IDs to the data for each screen, so that one data transmission to the host is not necessary. Data for multiple sides can be received upon request, and the display processing time when displaying multiple screens consecutively can be shortened compared to the conventional technology.
