DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to online system inquiry operations, and particularly to a transfer screen object management device for data transfer.

[Conventional technology]

Conventionally, there are two methods for displaying a screen from a host computer on the display unit of a terminal device in online system inquiry operations.

In the first method, a screen object is transmitted from the host computer side to the terminal device side for each screen display from the screen object storage file of the host computer.

The second method is to use a file transfer program to write the screen object storage file on the terminal device from the screen storage file on the host computer side before the inquiry process, and then write it to the screen object storage file on the terminal device from the host computer side during the inquiry process. When displaying a screen, the host computer side checks the switch in the screen object sent to the terminal device to determine whether the object is stored in the screen object storage file on the terminal device side. At this time, if the object is stored on the terminal device side,
A command is issued to output the screen object based on the screen name and the screen object storage file of the terminal device, but the screen object is not transmitted. Moreover, when the object is not stored, the screen object is transmitted.

[Problem to be solved by the invention]

The first conventional method described above has the disadvantage that the host computer is time-bound to transfer screen object data because the screen object is sent from the host computer each time the screen is displayed on the display of the terminal device. be.

In addition, in the second method, screen objects are not transferred from the host computer side to the terminal device side, so the host computer does not take time to transfer data, but (a) Uses a file transfer utility as a preliminary preparation. Must.

(b) Special specifications are required when generating screen objects.

(C) The screen on the terminal device side is fixed.

(e) When the number of terminal devices is large, it takes time to input screen objects.

There is a drawback.

[Means to solve the problem]

The transferred screen object management device of the present invention includes a screen storage means for storing screen objects transferred from a host computer in a screen object storage file in an external storage device on the terminal side, and a screen for writing management information of the file into a management table. a management means; a screen number monitoring means for monitoring the number of screen objects stored in the file;
A screen deletion means for deleting screen objects with a low screen usage rate from the file, a screen usage rate monitoring means for monitoring the usage rate of the stored screen objects, and outputting the screen objects from the file to a display unit of a terminal device. and screen output means.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of a transfer screen object management device according to an embodiment of the present invention. In the figure, a transfer screen object management device 1 is connected to a transfer screen object storage device 2 and a terminal device 3, and includes a screen management means 11, a number of one screen monitoring means 12, and a nine screen deletion means 1.
3 and 9 screen storage means 14, 9 screen usage rate monitoring means 15, and 2 screen output means 16.

The transfer screen object storage device 2 serves as an input device for the transfer screen object management device 1 when a screen object is sent from the host computer to the terminal device 3. The transfer screen object storage device 2 is composed of a magnetic disk device.

The terminal device 3 has an external storage device 4, and based on the output information from the transfer screen object management device 1, screen objects are written to or read from the external storage device 4, and the screen is displayed on the display section of the terminal device 3. Display.

The external storage device 4 has a screen object storage file, and all screen objects are stored in this file.

The screen management means 11 creates a management table 1 corresponding to the terminal device 3 according to the name of the terminal device to which the screen object is transferred.
7 is performed and the information in the management table 17 is updated.

The screen number monitoring means 12 monitors the number of registered screen objects by referring to the information in the management table 17 retrieved by the screen management means 11.

When the screen number monitoring means 12 determines that the number of registered screen objects has been exceeded, the screen deletion means 13 deletes the information from the management table 17.
Refer to and delete the screen object with the lowest screen object usage rate.

The screen storage means 14 stores the screen object in the external storage device 4.

The screen usage rate monitoring means 15 calculates the screen object usage rate in the management table 17 based on the transferred screen object name.

The screen output means 16 requests the terminal device 3 to display a screen object.

FIG. 2 is an explanatory diagram showing the management table 17 that is written or referred to by the transfer screen object management device 1 when a screen object is output from the transfer screen object storage device 2 to the terminal device 3. In the figure, the terminal device name 21 is the device name of each terminal registered at the time of environment setting of the computer system. The number of screen objects stored 22 indicates the number of screen objects stored in the external storage device 4 connected to the terminal device corresponding to the terminal device name 21. The screen object name 23 is specified when the screen object is created, and this screen object name is also used when the screen object is retrieved from the transfer screen object storage device 2. The screen object usage rate 24 contains a value calculated by the screen usage rate monitoring means 15 each time a screen object corresponding to the screen object name 23 is read from the external storage device 4 connected to the terminal device 3.

There are multiple tables of screen object names 23 and screen object usage rates 24 for the terminal device name 21, and these are considered as one block. The management table 17 includes blocks for the number of terminal devices connected to the host.

FIG. 3 is an explanatory diagram showing the operation of the transfer screen object management device 1. As an initial condition, it is assumed that no screen object is yet stored in the external storage device 4 connected to the terminal device 3.

First, when the AP (application program) 35 issues a screen display request to the terminal device 3, the transfer screen object management device 1 refers to the block 33 of the terminal device 3 in the management table. As described above, since no screen object is stored in the external storage device 4 of the terminal device 3, no screen object is registered in the block 33. Therefore, the transfer screen object management device 1 transfers the screen object from the transfer screen object storage device 2 to the external storage device 37 and displays it on the display unit of the terminal device 3. In addition, the number of screen objects stored in block 33 of the management table 225 screen object name 239
The screen object usage rate 24 is updated at the same time.

Next, when the AP 35 requests the terminal device 3 to display the same screen as above, the transfer screen object management device 1 refers to the block 33 of the terminal device 3 in the management table. At this time, since the screen object name is registered in the block 33, the transfer screen object management device 1 can recognize that the screen object is stored in the external storage device 37. Therefore, the transfer screen object management device 1 displays the screen image on the display section of the terminal device 3 by simply transferring a command to read the screen object from its own external storage device 37 and a few bytes of the screen name to the terminal device 3. be able to.

The above-described operations are repeated, but when several types of screen objects are transferred to the same terminal via the transfer screen object management device, the management table 17 provided for each terminal becomes full. At this time, the screen number monitoring means 12 passes control to the screen deletion means 13. Screen deletion method 1
3 refers to the screen object usage rate in the management table 17 calculated by the screen usage rate monitoring means 15,
When the screen object with the lowest usage rate is deleted from the external storage device 4, the information in the management table 17 is also deleted.

〔Effect of the invention〕

As described above in detail, according to the present invention, screen objects can be automatically stored in the external storage device of the terminal by using the transfer screen object management device, so frequently used screen objects can be In the second and subsequent transfers to the terminal side, the screen object can be displayed on the display section of the terminal device using only a command to read the screen object from the external storage device connected to the terminal device and the screen object name. Therefore, there is no need for the host computer to spend time and perform complicated transfer processing to transfer screen objects.
