DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overlay differential initialization display method, and more particularly, to an overlay differential initialization display method for reducing the time required to redisplay a screen in a terminal computer of an online system.

[0002]

2. Description of the Related Art A conventional technique will be specifically described below.

Conventionally, in this type of overlay method, only a part having a fixed format, such as a ruled line, is extracted from screen information displayed on a terminal computer and stored in advance in the terminal computer as a form overlay file. The host computer does not transmit all the screen information to be displayed to the terminal computer, but transfers the screen name identifying the form overlay file to be used and the screen data not included in the form overlay file, and transmits the data to the terminal computer. Reduce transfer volume.

One example of a conventional overlay method is disclosed in
No. 5811. The overlay method described in this publication is based on the fact that the image data is present in the terminal computer side in association with the form overlay information, so that the image data can be transmitted to the terminal printer without transmitting the same huge image data from the host computer side. It is possible to output to.

[0005]

The first problem is that, in the prior art, the data transfer amount is reduced in order to speed up the response of the terminal computer, but the time for redisplaying the screen is reduced. That is, no optimization has been performed. A terminal computer that can display a graphical screen has an order of magnitude more information than a conventional terminal computer that can only display characters (character terminals). Screen refresh time cannot be ignored. The reason is that the conventional overlay method has a function of reducing the data transfer amount between the host computer and the terminal computer to shorten the response time of the terminal computer, and does not include a means for reducing the time for screen display. is there.

An object of the present invention is to provide an overlay differential initialization display method capable of shortening the time required for a terminal computer to display data on a screen and shortening the response time.

Another object of the present invention is to provide an overlay differential initialization display method for reducing the time required for redisplaying the screen of the terminal computer and shortening the response time of the terminal computer without being conscious of the host program. Is to do.
