First Claim
1. A screen display control method in a terminal equipment having a display screen to be connected via a communication line to a host computer comprising the steps of:
- (a) providing a file of screen data and a table in which relational data between display screen data, input data to identify screens, and next screen data associated therewith are registered;
(b) when a screen data being currently displayed is beforehand registered as a display screen data in said table, retrieving, in response to inputting of a selected screen indentify data, from said table next screen data registered in association with the display screen data and the input data so as to read the next screen data from said file and displaying the screen data on said display;
(c) when the screen data being currently displayed is not beforehand registered as display screen data to said table, transmitting, in response to inputting of the selected screen identify data, the input data or data associated therewith to said host computer communicating with said terminal in order to request next screen data or information specifying the next screen data.

Abstract
In a screen display control of a terminal effecting screen display through communications with a host computer via a communication line, there are provided on the terminal side a file in which screen data to be frequently used is subjected to a download or is loaded and a reference table to which a systematic correspondence list associated with display screen data, screen selection data, and next screen data is registered. When screen data being displayed on a display of the terminal is already registered as display screen data to the reference table, if screen select data is inputted, the next screen data registered in association with the corresponding display screen data and the input select data is retrieved from the reference table so that the next screen data is extracted from the screen data file so as to be displayed on the display. When the screen data being displayed is missing in the reference table, in response to an input of the next screen select data, the input data or information associated therewith is transmitted to the host computer so as to request for the next screen data or information specifying the next screen data.

6. A screen display control method in a terminal equipment which has a display and which is connected via a communication line to an external system comprising the steps of:
-
(a) providing a file of screen data and a table in which relational information between display screen data, input data to identifying screens, and next screen data associated therewith is registered; (b) checking whether or not a screen data being displayed on said display is beforehand registered as a display screen to said table so as to judge whether or not said screen data is already registered; (c) when it is found in the step (b) that said screen data is already registered, in response to an input of a requested screen identify data, retrieving from said table next screen data registered in association with the display screen data so as to read the next screen data from said file and displaying the screen data on said display; and (d) when it is found in the step (b) that said screen data is not beforehand registered as display screen data to said table, in response to an input of a requested screen identify data, transmitting the input data or data associated therewith to the external system in order to request next screen data or information specifying next screen data. - View Dependent Claims (7)

8. A screen display control system of a terminal which has an input device and a display and which is connected via a communication line to an external system comprising:
-
a file of screen data and a table to which correspondence relationships between display screen data, screen identify input data, and next screen data are registered; means for checking whether or not screen data being displayed on said display is beforehand registered as a display screen to said table so as to judge whether or not said screen data is already registered; means responsive to a first result of said judge means for determining that said screen data is already registered in said table, in response to an input of a requested screen identify data from said input device, and retrieving from said table next screen data registered in association with the display screen data so as to read the next screen data from said file, and display the screen data on said display; and means responsive to a second result of said judge means for determining that said screen data is not beforehand registered as display screen data to said table, in response to an input of a requested screen identifying data from said input device, and transmitting the input data or data associated therewith to the external system to request and obtain next screen data or information specifying the next screen data.
