Menu | <<<< | >>>> | Modifications are made to the definition workbook

The active model definition workbook is modified temporarily so that you can click buttons to expand your model.  The expanded set of codes will result in a new model definition workbook, a new data workbook, and a new equation workbook.  Procedures on the Model Manager control screen will then put your old data and equations into the new workbooks.  Here you see the definition workbook ready to be modified.
