PROBLEM TO BE SOLVED: To suppress memory resource consumption to a necessary irreducible minimum even when objects are added to a source object by storing respective pieces of attribute information on objects which can be plotted alternately and associatively with the source object together with source attribute information on the source object. SOLUTION: A computer system 301 plotts an object represented by abstracting, for example, a figure, a color, etc., on the editing screen of a display part 305 according to inputted attribute information. Then a memory part 303 is stored with pieces of attribute information on objects that can be potted alternately and associatively with a specified arbitrary object as a source object together with source attribute information on the source object. Therefore, the attribute information regarding the added object is only stored as associated information together with the source object, and the need to secure a memory area for storing the whole page including the added object is eliminated. |
