PURPOSE:To attain a flexible correspondence even if the system of a calculation expression changes due to the change of a work by providing a calculation expression input means inputting the calculation expression, a calculation expression syntax analyzing means, data item means, a data item obtaining means or the like. CONSTITUTION:The calculation expression input part 1 inputs the prescribed calculation expression and the calculation expression which has been inputted to a calculation expression storage part 4 is stored, a calculation expression syntax analyzing part 7 checks the righteousness between an operator and an item. To put it concretely, whether a calculation item exists in a data item and a data table is recognized, and a system is developed into an execution system in which calculation is easily executed. In the case of the data item, it is inputted from a data item input part 2 in an interactive system, and a data item storage part 5 stores the input data item, whereby the data item obtaining part 8 extracts individual data of the items for calculation from a file. Furthermore, the input image of the data table is inputted from a data table input part 3 in the interactive system, and data is easily corrected and deleted. Thus, the flexible correspondence is attained even if the system of the calculation expression changes due to the change of the work.
