Abstract
A method of controlling the selections on a reproducible control data structure with two different selection control methods. According to a first control method, single frame plural selectors, to each of which a numerical identifier has been added, are displayed. Branch tables grouping branch data according to selector numbers are provided. A user makes a selection by selecting a selector number. According to a second control method, plural sectors are displayed in a single frame. A user-specified selector and other selectors are provided for visually differentiating between the selectors as a means of prompting user confirmation of the specified selector. A selection confirmed by the user controls the selection by means of the branch data. Branch data usable by both the first control method and the second control method is grouped together by providing the branch data used by the second control method in the branch table used by the first control method.
