Use the Parameter Control Panel to see what variables have been controlled, either interactively or from the Import Data dialog box, and to control variables. It's a dockable panel and can be opened by selecting Open Parameter Control from the Window menu.
Add a variable to the list. The Find window will open. Select a variable and it will be added to the list. If the variable is arrayed, the Choose Subscript dialog box will open. You can control each element of an array, but you have to select them one at a time.
Shows the list of all variables that have values set on them. Everything not in this list will use the equation specified for it when it's computed.
Variable is the name of the variable being controlled. In an array, it will be the array element (Population[DadeCounty]).
Value is the value the variable will take on instead of the value specified by its equation. For stocks, this will be the new initial value for the stock. For everything else, it will be the value throughout the simulation (except that flows may be further constrained to a different value, depending on their associated stock values). Type in a new value to change this.
Note: Values will be shown with a highlighted background when they're different from what the default (equation or import link) value would be. If the equation wasn't a constant, it will always be highlighted.
Equation Value is the value in the equation. This will display NA for variables that don't have a constant equation.
Source specifies the source of the specified value. These can come from two places:
Import Link indicates that the value was set from an import specified in the Import Data dialog box.
Remove the parameter control, setting the value back to the equation (or the Import Link value, if this variable has an import link). This is only active for Interactive controls.
Copy to Clipboard will copy the names and values active in the dialog in a format that can be pasted into a Parameter sheet.
Create Import Sheet will prompt you for the name of a file to save the current control values to. The file can subsequently be used as a Parameter sheet.
Set all constants to equation of imported value will reset everything in the list that is imported or has a constant equation to the corresponding value. Nothing will be removed from the list, but the values will be the same as they would be if the item were removed. This action won't change overrides of variables that aren't constants.
