PURPOSE:To cope with the revision such as increase in number of parameters, etc. without program change by dividing a picture into lines and characters or pictures and symbols and adding a procedure generating a respective divided pattern component. CONSTITUTION:When the information relating to picture transition is inputted from a keyboard, a selector 2 selects an identifier of a picture data group to be displayed next among plural identifies and the selected data group is prepared with a corresponding display procedure. The selector 2 requests the execution of the procedure corresponding to a procedure interpreter 3, which executes the procedure to generate a picture. The data group of the lowest level O represents the display of the minimum unit and has a specific display procedure respectively, while the procedure is the same for the higher level 1 even when the identifier of the data group differs. Thus, the generation of different picture is facilitated by giving identifiers D, E to a data B of the same procedure and identifiers F, G to a data C.
