Abstract

PURPOSE:To reduce the burden on a system designer and developer by registering data inputted by a terminal operator in a temporary file in the middle of the advance of transaction processing and specifying input data of transaction processing, whose processing process the terminal operator requests confirmation, from the temporary file. CONSTITUTION:When receiving the transaction processing process confirmation request from the terminal operator in the middle of the advance of transaction processing, a control program part 101 uses a management table 101a to extract the latest input data out of input data received from the pertinent terminal from a temporary file 103. Picture data corresponding to this input data is extracted from a picture library 102, and both of them are displayed on a terminal 104 again. Consequently, it is unnecessary for a user program to consider a special coping method for the transaction processing process confirmation request from the terminal operator in the middle of the advance of transaction processing when an application program for plural transaction processings is designed and developed. Thus, the burden on the user program is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a screen redisplay method, and more particularly to a method in which a control program processes a terminal operator's transaction processing progress confirmation request while the transaction processing is in progress.

Prior Art In the conventional system, the control program does not process the terminal operator's transaction processing progress confirmation request.Therefore, the user program sequentially outputs messages indicating the progress of the transaction processing to a specific terminal device. This message should be acknowledged by the terminal operator or
Alternatively, it was necessary to devise a way to process the transaction processing progress confirmation request in the user program.

Problems to be Solved by the Invention Normally, business performed on a computer consists of multiple transaction processes.1 Each transaction process uses a dedicated screen, and a terminal operator enters data interactively on this screen. , proceed to the next transaction process, and as the scale of the business to be handled increases, the number of transaction processes increases, the relationship between them becomes complex, and the progress paths of transaction processing are diverse. Operators may want to check where the transaction processing they are currently performing is positioned in the overall business, and what route the current transaction processing took.

The current control program does not have a means to respond to the terminal operator's transaction processing progress confirmation request that occurs at unexpected times.Therefore, it is necessary to devise a user program to handle this request. This is a burden on system designers and developers of business systems.

The present invention has been made in view of the above-mentioned conventional situation,
Therefore, an object of the present invention is to provide a novel screen redisplay method that makes it possible to solve the above-mentioned problems inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the screen redisplay method according to the present invention includes a means for the user to specify the number of transactions to be confirmed at the time of execution, and a temporary work use for the specifying means. means for preparing a file and its management table; registration means for registering data input by a terminal operator in the temporary file during transaction processing; request means for requesting confirmation of the progress of transaction processing by the terminal operator; and identifying means for identifying input data for transaction processing requested by the means from the temporary file, and receiving the request from the terminal operator.

EXAMPLE Hereinafter, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention when processing a transaction processing progress confirmation request from an operator of a terminal 104 using a control program section 101 according to the present invention.

Referring to FIG. 1, the control program section 101 stores the temporary file management table 101a when executing the user program.
, and allocates a temporary file 103 that has a capacity to hold all the input data for the number of screens specified by the user in execution 1cL.During transaction processing, the control program unit 101 receives a screen display request from the user program. 105, the screen data of the corresponding screen is extracted from the screen library 102 and displayed on the terminal 104. The terminal operator inputs necessary data on the displayed screen and transmits it to the control program section 101 (106). In process 1, the control program unit 101 passes input data to the user program and also records it in a temporary file 103. At this time, the correspondence between the recording position in the file 103 and the screen name is temporarily recorded in the management table 101a. When the control program unit 101 receives input data from the terminal 104, it sequentially performs the above-mentioned processing, and when it receives a transaction processing progress confirmation request from the terminal operator while the transaction processing is in progress, the control program unit 101 performs processing 2. , here, using the management table 101a, the latest input data received from the relevant terminal is extracted from the temporary file 103, screen data corresponding to the input data is extracted from the screen library 102, and both are combined. It is redisplayed on the terminal 104. At this time, the input data has already been passed to the user program and is being processed by the user program, so the terminal 10
The screen redisplayed in step 4 cannot be rewritten by the operator. Furthermore, when a transaction processing progress confirmation request is issued by the terminal operator, the above process 2 is repeated, and the second most recent input data is subject to redisplay, going back from the time when the first confirmation request was issued. do. The current screen will be redisplayed in sequence until the terminal operator issues a request to redisplay the current screen.

Next, FIG. 2(a) shows the correspondence between the processing l111 of the control program unit 101, the management table 108 used in processing 2, and the temporary file 109, and for the sake of explanation, the structure of transaction processing is shown in FIG. 2(b). ).

As shown by the bold lines in FIG. 2(b), 11.21, 32.
41, the control program section 101 records the data input in each transaction process in the temporary file 109, and also registers the recording position and the screen name used for input in the management table 108.

The recording position and registration position are performed from the first record of the temporary file and the first record of the management table, respectively. Therefore, the names of the screens used in transaction processing 11, 21, and 32 are registered in management table 1.2.3, respectively. , the input data of the screen is sequentially recorded in the temporary file 109. Then, the control program unit 101 stores the registration position of the current transaction process in pointer b.When the transaction process has progressed to 41, when the terminal operator receives a request to confirm the progress of the transaction process, the control program unit 101 stores the registration position of the current transaction process in pointer b. The screen name and recording position are obtained from the management record 3 that was registered one before the management record 4, the corresponding input data is extracted from the temporary file 109, and it is redisplayed on the terminal 104 together with the screen data. At this time, the position on the management table of the management record on the redisplay screen is memorized in pointer a, and when a confirmation request is received again, the management record registered one before the management record 3 indicated by pointer a is Processing is performed using record 2, and pointer a is updated to management record 2.

In the registration means described above, if the management table and temporary file reach their capacity at the time of registration, the first record is re-registered and used cyclically. Similarly, when extracting, when the first record is reached, the next pointer a points to the last record 5.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, when a terminal operator is proceeding with transaction processing in the form of interaction with a screen displayed on a terminal device, a control program displays data input by the terminal operator on the screen. At the request of the terminal operator, at any point during transaction processing, data can be entered in the past transaction processing screens and this screen sequentially, going back in time. The data can be displayed.

Therefore, according to the present invention, when designing and developing a business program that processes multiple transactions, the user program has a special method for responding to a transaction processing progress confirmation request from a terminal operator that occurs during transaction processing. Since there is no need to take this into consideration, the effect of reducing the burden on the user program can be obtained.
