A method for handling loops in calculation formulae employing a data processing system (4, fig. 2), according to which as the value of each dependent variable is calculated for the first time such action is recorded on a list (205, fig. 4A). The list is checked before each calculation (208), and no recalculation of a dependent variable is permitted if a value for it has already been calculated since the current list was started. |
