PURPOSE:To reduce the capacity of a file, by inputting data in accordance with a display field define deck which is produced by reading out necessary divisions from a file and coupling the divisions with each other. CONSTITUTION:Display field define deck constituting a business is divided into divisible units, for example, pages and the display field define deck are held in a file on the basis of the divisible units. Any picture defining body which cannot be divided into pages, if exists, the body is held business by business. If one display field define deck can be defined when it is combined with another display field define deck or division for one business, the combination number is stored. Since it can be known that the display field define deck of a business N is constituted of divisions a1 and a3, the divisions a1 and a3 are continuously read out from the file when the display field define deck of the business N is read out. Moreover, since it can be known that a business C can be obtained by coupling the display field define decks of businesses A and B with each other, the display field define decks of the businesses A and B are continuously read out from the file when the display field define deck of the business C is to be obtained. Therefore, the quantity of necessary files can be reduced. |
