PURPOSE:To improve the processing speed of a table calculation processor. CONSTITUTION:When a calculating formula for determining the value of a cell in a table is inputted from an input device 2, a syntax analysis means 13 and a recalculation implantation form generation means 14 generates the implantation form of the calculating formula and a recalculation implantation form storage means 15 stores the generated implantation form in a recalculation implantation form array 5. When the value of the cell is inputted from the input device 2, a data storage means 12 stores the value in a data array 4 and judges whether it is necessary for a recalculation implantation request means 16 to perform a recalculation or not. When it is judged that the recalculation is necessary, a recalculation implantation form call means 17 performs a recalculation by using the implantation form stored in the recalculation implantation form array 5 and the value of the cell stored in the data array 4. Because the implantation form of the calculating formula is not necessary to be generated every time the recalculation is performed, processing speed can be improved. |
