Menu | <<<< | >>>> | [Change Exogenous Variable] – click to record your changes

Here changes in the variable EfsNUT have been entered manually in the ‘Change?>’ line.  Clicking the [Change Exogenous Variable] button records the changes for the next simulation and re-draws the chart with the changes and the previous values for comparison.  Other exogenous variables can be changed by clicking the [Select a Variable] button and repeating this process.  When done, click the [Return to DEMOmod Model] button to go back to the {Model} sheet for simulation of the model with the changed exogenous variables.  After a solution has been saved, the exogenous variables all revert to their original values and other alternative solutions can be generated in a similar manner.
