PROBLEM TO BE SOLVED: To easily recognize a changed part by adding specified coloring or meshing to the changed part between unupdated and updated documents when updating the document. SOLUTION: When the document is changed after an environment is set, coloring or meshing designated in environment setting is displayed at the changed part. In this case, since unchanged information is preserved in a memory as well, the changed part can be returned into unchanged state as well. When one numerical value 53 in the list of an unchanged document 51 is changed into a changed numerical value 55 of a changed document 52, for example, the numerical value directly changed by a user is meshed and displayed like the changed numerical value 55. At that time, one arithmetic result 54 in the unchanged document 51 changes one numerical value 53 so that the arithmetic result 54 can be automatically displayed like one arithmetic result 56 in the changed document 52 as well. Then, the changed parts are simultaneously meshed and displayed like one arithmetic result 56 in the changed document 52. |
