Abstract

PURPOSE:To reduce the memory of a user program and to reduce the use time of a display terminal equipment for screen display by sharing the storage area of screen format data in one place, and controlling the data at a screen control table. CONSTITUTION:When the screen control table 8 is retrieved and there is no screen name concerned, screen format data FD fitted to the screen name is read from a magnetic disk device 10 to a screen format data storage area 9 and the screen name is registered in the screen control table 8. Screen data transmitted to a display terminal equipment 11 from screen format data FD is generated and generated screen data is transmitted to the display terminal equipment 11. Thus, the screen where a transmission instruction is executed is displayed from the user program 6. The memory of the user program 6 is reduced and the use time of the display terminal equipment 11 for screen display can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a screen display control method, and more particularly to a screen display control method for displaying screens using the same screen in a plurality of user programs.

[Prior Art] Conventionally, this type of screen display control system has an area for storing the screen format for each user program, and even when using the same screen, the screen format is stored for each user program. The screen was displayed by reading the screen format into the area from the medium that was being used, creating screen data to be sent to the display terminal device.

[Problems to be Solved by the Invention] In the conventional screen display control method described above, when the same screen is displayed by multiple user programs, an area for storing the screen format is reserved for each user program. Increases program memory. Furthermore, since the screen format is read for each user program from the medium in which the screen format data is stored, there is a drawback that the CPU time increases.

Therefore, an object of the present invention is to provide a screen display control method that solves the above problems by sharing an area for storing screen formats and managing the screen format using a screen control table.

[Means for Solving the Problems] The screen display control method of the present invention includes a screen name receiving means for receiving a screen name to be displayed on a display terminal device from a user program, and searching the received screen name in a screen control table. , screen control table search means for recognizing that screen format data corresponding to the screen name has been read into the screen format data storage area;
When the screen control table search means cannot recognize the screen, the screen format data reading means reads the screen format data corresponding to the screen name into the screen format data storage area, and the screen data is retrieved by referring to the read screen format data. The present invention is characterized by comprising screen data creation means for creating screen data, and screen data sending means for sending the created screen data to the display terminal device.

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

FIG. 1 is a block diagram of an embodiment of the present invention. The present invention
Screen name receiving means 1 and screen control table searching means 2
, screen format data reading means 3, screen data creation means 4, and screen data sending means 5.

FIG. 2 is a processing flow diagram of one embodiment of the present invention, and the third
The figure is a block diagram of this embodiment.

Referring to FIG. 3, this embodiment includes a user program 6, a control program 7, a screen control table 8, a screen format data storage area 9, a magnetic disk device 10, and a
It is composed of one display terminal device 11.

The magnetic disk device 10 stores many screen format data FDs in advance, and these screen format data FDs are stored in the screen format data storage area 9 in response to a call from the control program 7.
is loaded into. The display terminal device 11 displays screen data by sending the screen data from the control program 7. The screen control table 8 is a table that stores screen names read into the screen format data storage area 9 by the control program 7.

Next, the operation of this embodiment will be explained along the processing flow shown in FIG.

By executing the transmission command from the user program 6, processing shifts to the control program 7, which receives the screen name attached to the transmission command (step 1 in FIG. 2). The control program 7 searches the screen control table 8 for the screen name in order to recognize whether the screen format data FD corresponding to this screen name has been read into the screen format data storage area 9 (step 2). If the screen control table 8 is searched and there is no corresponding screen name, the screen format data FD corresponding to the screen name is read from the magnetic disk device 10 into the screen format data storage area 9, and the screen name is registered in the screen control table 8. (Step 3). Screen data to be sent to the display terminal device 11 is created from the screen format data FD (step 4). By transmitting the created screen data to the display terminal device 11 (step 5), the screen on which the transmission command was executed by the user program 6 is displayed.

[Effects of the Invention] As explained above, the screen display control method of the present invention shares the storage area of screen format data in one place,
By managing this using a screen control table, it is possible to reduce the memory of the user program and also to reduce the usage time of the display terminal device for displaying the screen.
