Abstract

PURPOSE:To use the inputted data without inputting again the original image even though this image is erased by storing the inputted data and displaying again this data on a display screen to reuse it. CONSTITUTION:A screen store control means 41 stores the data received from a text editing means 31 into a storage area. At the same time, the means 41 takes the data out of the storage area by an amount equal to one screen when an input data deciding means 13 decides that the input data received from the terminal 11 requests the re-display of the preceding screen and transfers the data to a terminal input/output means 12 via the means 31. Then a cursor is set at the data on a line mode screen and one or more characters are input ted. Thus, the relevant data can be reinputted. However, a terminal user produces a display request of the preceding screen when the image of the desired data to be used for reinput is erased by mistake owing to the output of a mes sage given from an application program. Thus, the data on the preceding screen stored in a storage is read out and displayed again. As a result, the inputted data can be inputted again without inputting again an original image.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to means for utilizing a time sharing system in a terminal connected online to a host computer.

〔overview〕

The present invention provides a means for reusing inputted data using data on a display screen, in which the inputted data is stored and the image is erased by displaying and using this data again on the display screen. Even if the data is lost, the entered data can be used without having to re-enter the original image.

[Conventional technology]

In the conventional example, the cursor is placed on the input data displayed on the display and one or more characters are input, and the input data is used for re-input. However, there is a restriction that the data cannot be reused unless the image of the data input last time remains on the display at the time of re-input.

FIG. 4 is an explanatory diagram of a method of using conventionally input data for re-input. A screen 51 is a screen on the display of the terminal 11 and shows the state before re-input. A screen 52 shows a state in which re-input processing is performed using the screen 51. The area configuration 53 is an area configuration indicating the configuration of the area of the screen 52. The re-input noise buffer 61 has a storage area 32 for the maximum number of lines per screen.
The data contained in the input buffer is transferred when the input data is used and re-input is performed.
Reference numeral 2 denotes a buffer for passing the data of each code transferred from the re-input buffer 61 to the input/output receiving means 22.

Here, while input processing is performed on the terminal 11 and the screen 51 is displayed on the display, use the command A (execute file/PL-A) that has already been input to execute a similar command (file /PL-8), the terminal user places the cursor on command A that remains on the screen and overwrites the part of the file /PL-A that should be changed with /FL-8. Press the send key (see screen 52). Here, if you want to re-enter command A as it is, you can enter any character, so just enter one or more characters.

■ The screen image is divided into a message output area from the host side and an input area from the terminal 11 (see area configuration 53: ■ message output area from the host side,
The input area from the terminal 11 of the image of the screen 52 is collected and stored in the re-input buffer 61. Note that if even one character is input into the input area from the terminal 11, it is assumed that all the characters in that input area have been input, and the records of the entire input area are transferred to the re-input buffer 61.

At this time, data in each input area is separated by code MTB.

(2) The text editing means 31 scans the input area in the re-input buffer 61 and transfers the record in the first area of the areas where - characters or more have been input to the input buffer 62.

■ When the input/output reception means 22 receives a data input request from the application program 21,
The record is taken out from 2 and passed to the application program 21.

(2) If there are multiple areas in which input has been made in the re-input buffer 61, the processes (2) and (2) are repeated until the last input record.

[Problem that the invention seeks to solve]

In such a conventional example, the re-input function is used only for the data that is being displayed on the display at the time the user wants to re-input. It depends on the type of display, but in general, if you try to display more lines on the screen than the maximum number of lines for that display, the first line of the screen will be overwritten by the amount exceeding the maximum number of lines, or the maximum number of lines will be overwritten. When this is exceeded, measures are taken such as clearing the entire screen and displaying the remaining lines starting from the first line of the screen. Therefore, when inputting similar data repeatedly, the image of the data that you want to use for re-input may disappear due to output of messages from the application program or other processing related to the input operation itself. If you do, you will have to input the original image again, which has the disadvantage that the input data cannot be used effectively.

The present invention aims to eliminate such drawbacks, and aims to provide an inputted data reusing device that can effectively utilize inputted data even if an image desired to be used for re-input has disappeared.

[Means for solving problems]

The present invention converts this screen data into input data based on a key input of one or more characters indicated by a cursor that is aligned with the line mode screen data being displayed on the display surface of the computer and the output data from the computer. The computer is included in a data processing system comprising a storage control means having a storage means for sequentially storing incoming input data in its own storage device in correspondence with the output data. In the input data reuse device,
The terminal includes a function key that issues a previous screen display request, and the storage control means stores a screen that was displayed earlier than the screen data currently being displayed on the display surface of the terminal in response to the previous screen display request. The terminal includes an extraction means for extracting input data corresponding to the screen data specified by this request from the storage device, and the terminal stores the screen data extracted by the extraction means on the condition that the previous screen display request is issued. The present invention is characterized in that it includes a display means for displaying on a display surface of its own means.

[Effect]

You can re-enter this data by placing the cursor on the data on the line mode screen and typing one or more characters. However, if the image of the data that you want to use for re-input disappears due to the output of a message from an application program, and the terminal user issues a previous screen display request, the previous screen data stored in the storage device will be displayed. can be read out and redisplayed. Scan this and
It is possible to re-input already input data without having to re-input the original image.
