PURPOSE:To carry out the machine processing of office work efficiently and to prevent a copying error, calculation error, etc., by operating an input device directly in observing a display screen, and performing the tabulation of a necessary list, definition of a calculation expression, etc. CONSTITUTION:Pieces of position and direction information are stored in a list data storage area 7 successively by a rule drawing control part 9. Those data are stored in specified addresses of a cursor of the area 7 successively by a character string entry control part 10. At the same time, the data are displayed on the display screen of a display part 15 under the control of a display control part 16. Then, coordinate information and arithmetic symbols are combined to define the calculation expression between internal list frames under the control of a calculation expression definition control part 11, thereby storing it in a calculation expression storage area 8. Then, data in the frame in the list are extracted according to the calculation expression to perform calculation under the control of a calculation execution control part 12. Then, the result is displayed on the display screen while stored in the area 7, and further printed 6 under the control of a printing control part 14. |
