Note You cannot use the FPScript Debugger to check the code at this point, since no data is present yet. To make sure that the calculation works properly for indexing, it is recommended that you import a typical data set to which the calculation can be applied and enter the code for the calculation on the Calculations tab in the Properties dialog box of this data set. In the Edit Calculation that now appears, you can use the FPScript Debugger to test the code.
