BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to online on-line processing, and more particularly to an online screen display scroll system for controlling screens in an online program on a host computer.

[0002]

2. Description of the Related Art Generally, in an online immediate processing program, there are a method of inputting and processing data in one format screen and a method of performing screen development corresponding to the processing by a plurality of format screens to perform one processing. is there.

When one process is performed using a plurality of format screens, data is transmitted to the program from an appropriate data input terminal on the first format screen displayed on the terminal. In the host computer, the data received from the terminal is edited by the communication management means and the format screen management means, and the necessary data is passed to the program. In the program, after performing the processing according to the input data, the second screen and the data to be displayed on the same screen are passed to the format screen management means, and the second screen is transmitted from the means to the terminal through the communication management means.

Here, in order to allow the terminal operator to perform an operation for viewing the information on the previous screen while the second screen is being displayed, a certain keyword is received in the program, or a certain keyword is displayed on the screen. A logical structure for transmitting the first screen when the data instructing the previous screen display is input and received in the item is incorporated into the program, and a logical structure for returning the first screen to the current screen display is incorporated.

Similarly, after the nth screen is displayed, the immediately preceding screen (n-1th screen) or the previous screen (n-2nd screen) is displayed.
Is displayed, or the previous screen (n-1 screen) is returned to the current screen, or the previous screen (n-2 screen) to the previous screen (n-1 screen) or the current screen (n screen) ) Incorporate the logical structure for returning to the display within the program or each program group.

[0006]

In the conventional online program, a logical structure for switching from the current screen to the previous screen display or from the previous screen display to the next screen display must be provided inside the program. There's a problem. In addition, when there are several process steps (screen expansion) to reach the current screen, the logic structure for screen control in the program becomes complicated.

It is an object of the present invention to solve the above problems and provide screen scrolling by a specific key input without incorporating a logical structure for screen control inside a program.

SUMMARY OF THE INVENTION The present invention is a system for managing screens displayed on a terminal device by a single program or a plurality of programs of an online immediate processing system in accordance with a processing flow. Communication management means for communicating with the terminal, and a database management means for creating a data to be edited by editing the stylized format of the screen displayed on the terminal and the format for exchanging data with the program, Online program group for performing interactive online immediate processing, means for managing format editing of data to be displayed on the terminal in the program, and screen information to be format edited, and data from the program at the time of passing to the managing means And a format history screen information, a display destination terminal information, and a transmission order are stored in a screen history file by a screen history management means. It is made.

[0009]

The present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an operation sequence in one embodiment of the present invention, and FIG. 2 is a diagram showing a record layout showing information stored in the screen history file in FIG.

1 and 2, an embodiment of the present invention is an online instant processing system, in which screens displayed on the terminal device 11 by a single or a plurality of programs are managed in accordance with the processing flow. By using the online screen display scrolling method, the communication management means 10 for communicating with a plurality of terminals and the format for the screen displayed on the terminal 11 and the format for exchanging data with the program are edited, In a computer system including a database management means 6 for creating data to be transmitted and an online program group 7 for performing interactive online immediate processing, data 25 to be displayed on the terminal device 11 in the program and a screen to be format edited A screen editing management means 9 for managing format editing of the information 24, and a program for the screen editing management means 9. Of data 25 and the format editing screen information 2
3 and the display destination terminal information 21 and the transmitted order 22 are included in the screen history file 3 and the screen history management means 8 is stored, and when the display instruction data of the previous screen is received from the terminal device 11 next, The screen history management unit 8 collects the stored information from the screen journal file 2, transfers it to the screen editing management unit 9, displays it on the terminal, and when the next screen display instruction data is received from the terminal, the screen history management The means 8 collects the stored information from the screen journal file, transfers it to the screen edit management means 9, and displays it on the terminal.

First, in the previous processing step in which the program 7 tries to display the current screen, the READ command is supplied to the database management means 6 in step a, and the database 1 searched in step b is searched for data. Database management means 6
Stores the data in the data journal file 2.

When the program 7 performs the screen transmission process, the screen history management means 8 is instructed to transmit the screen in step c. The screen history management means stores the screen information to be sent in the screen history file 3 while notifying the screen editing management means 9 of screen editing and transmission.

As shown in FIG. 2, this screen information includes a destination terminal code (terminal ID) 21, a serial number 22 sent for each terminal, a screen name 23 to be sent, control information 24 sent from a program, and a screen text. It consists of data 25.

In the process of screen editing and screen text transmission, steps a to h are performed in the same manner as in the conventional case, but the screen editing management means 9 searches the screen file 4 for a screen and acquires the screen data. The screen editing management means 9 is a communication management means 10.
The edit screen is notified to and stored as transmission data in the transmission queue storage file (output queue) 5. The communication management means 10 takes out the stored edit screen as a queue and sends it to the terminal device 11.

Next, in step i, the previous screen display code is received by the communication management means 10 by pressing the pre-screening request key, which has been agreed in advance, from the terminal 11. The communication management means 10 notifies the screen history management means of this via the screen editing management means.

In step j, the screen history management means 8 searches the screen history file 3 for the latest screen having the terminal number, and acquires the screen name and program data. In addition, it notifies the program that the previous screen display request has been issued, if necessary.

In step k, the screen history management means notifies the screen editing management means that the screen information acquired in the previous stage will be edited and transmitted.

In steps 1 to p, the screen is transmitted according to the above procedure even when the conventional process of transmitting screen information and screen text is requested.

As can be seen from the above operating conditions, the screen history management means 8 sends the previous screen or the next screen, and the program does not have a logical structure for sending the previous screen or the next screen. The screen display required by the operator can be displayed.

[0020]

As is apparent from the above description, according to the online screen display scrolling method of the present invention, the program determines the request data of the previous screen and the next screen or the transmission screen when the request data is received. It is possible to obtain the effect that the operator's request screen can be transmitted without having a logical structure for managing the.
