CONSTITUTION:In response to a command from the outside, format information corresponding to a picture displayed on a visible display device 2 is read out of a data base 3 by a maintenance processing part 12, and its read-out format information is corrected in accordance with a command, and thereafter, written in the data base 3. Thereafter, corrected format information is read out of the data base 3 by a man-machine interface processing part 11, and the picture on the visible display device 2 is changed to a picture based on the corrected format information. In such a way, the format information of the picture can be changed in a state that the picture for a work is displayed on the visible display device 2, and it becomes unnecessary to call a maintenance exclusive picture, therefore, the procedure for changing the format information of the displayed picture can be simplified, and a return to an original work can be executed quickly.

Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a screen changing method, and more particularly to a screen changing method for changing format information of a screen that is stored in a database and is currently being displayed.

BACKGROUND ART Conventionally, in a data processing system, when changing the format information of a screen currently displayed on a display device, the processing currently being performed is temporarily interrupted, and a replacement screen is displayed instead of the screen to be changed. A maintenance-only screen was called up and displayed, and format information was changed while looking at the maintenance selection screen.

In such conventional data processing systems, changes to the format information on a screen were performed while looking at a maintenance-only screen that was called up instead of that screen, so the operator was unable to perform the screen selection operations for the original work. Screen selection operations that are different from those required for maintenance must be performed on the maintenance-only screen, which has the disadvantage of complicating the procedure and requiring a staff member to return to the original work.

Purpose of the Invention The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional method, and it is possible to simplify the procedure for changing format information, and to quickly return to the original business. The purpose is to provide a screen change method.

Composition of the Invention The screen changing method according to the present invention is a screen changing method for a data processing system that includes a database that stores format information of a screen displayed on a display device, and in which information is changed from the database in response to an external command. reading means for reading out the format information; modifying means for modifying the format information read by the reading means in accordance with the command; and writing means for writing the format information modified by the modifying means into the database. and a changing means for changing the format information on the screen on the display device to the corrected format information written in the database by the writing device, while the screen is displayed on the display device, The present invention is characterized in that the format information is modified by the modification device, and after the format information is modified, the format information on the screen is modified by the modification device.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, a man-machine interface processing unit 11 in a data processing device 1 reads format information from a screen format information database (hereinafter referred to as database) 3 according to human input information from a keyboard unit 2a of a visual display device 2, and reads this format information. The screen display on the visual display device 2 is controlled based on this.

The maintenance processing section 12 changes the format information for both sides stored in the database 3 in response to a processing request sent from the man-machine interface processing section 11.

FIG. 2 is a flowchart showing the operation of one embodiment of the present invention. The operation of an embodiment of the present invention will be explained using FIG. 1 and FIG. 2.

When the format information of the screen is changed by the operator while the screen is being displayed on the visual display device 2, when the operator inputs a screen correction command from the keyboard section 2a (step 21 in FIG. 2). , the man-machine interface processing unit 11 sends the screen correction command to the signal line 10.
1, the analysis result is sent to the maintenance processing unit 12 via the signal line 102 as a processing request.
(Step 22 in Figure 2).

The maintenance processing section 12 transmits the corresponding format information from the database 3, that is, the format information corresponding to the screen currently displayed on the visual display device 2, to the signal line 103 in accordance with the processing request sent from the man-machine interface processing section 11. (step 23 in FIG. 2).

After analyzing the contents of the format information read from the database 3, the maintenance processing section 12 corrects the format information in accordance with the processing request sent from the man-machine interface processing section 11 (step 24 in FIG. 2).

When the modification of the format information is completed, the maintenance processing unit 12 writes the modified format information to the database 3 via the signal line 103 (step 25 in FIG. 2), and sends a notification indicating that the modification of the format information is completed. Signal line 104
The data is issued to the man-machine interface processing section 11 via the (step 26 in FIG. 2).

This completes the format information changing process in the maintenance processing section 12, but during this time both sides based on the format information before modification remain displayed on the visual display device 2.

When the man-machine interface processing section 11 receives the notification signal from the maintenance processing section 12, it retrieves the corrected format information from the database 3 via the signal line 105, and uses the iI visual display device 2 based on the corrected format information. The screen is redisplayed upwards (step 27 in FIG. 2). This completes the process for the screen correction command manually entered by the operator from the keyboard section 2a.

In this way, in response to an external command, the maintenance processing unit 12 reads format information corresponding to the screen displayed on the visual display device 2 from the database 3, and uses the read format information in response to the command. After correcting it, write it to the database 3, and then write it to the maintenance processing section 12.
Man-machine interface processing unit 1 that operates in synchronization with
1 reads the corrected format information from the database 3 and changes the screen on the visible display device 2 to a screen based on the corrected format information, thereby changing the business screen to the visible display device 2. It is possible to change the format information of the screen while it is displayed above.

Therefore, the format f of the currently displayed screen? When changing one report, there is no need to temporarily interrupt the process currently being performed and there is no need to call up a dedicated maintenance screen in place of the displayed screen to be changed. It is possible to simplify the procedure for changing the format information on the screen, and it is possible to quickly return to the original work.

Effects of the Invention As explained above, according to the present invention, format information is read from the database in response to an external command while the screen is displayed on the display device, and the format information is modified in accordance with the command. The procedure for changing format information can be simplified by writing it into the database and then changing the format information on the screen of the display device to the corrected format information written to the database. This has the effect of allowing a quick return to the original work.
