ABSTRACT:
A constraint-based spreadsheet system includes a direction discrimination section, a dependence information generating section, a program execution process information generating section, and a display section. The direction discrimination section discriminates whether constraint information, which corresponds to a formula which is a basic structural element of a program, has direction of calculation. The dependence information generating section generates dependence information between tables and within a table based on the direction of calculation discriminated by the direction discrimination section. The program execution process information generating section generates program execution process information using the dependence information. The display section displays the program execution process information.
