- | **Binding Variable** - A simulator variable which is linked to two different variables from the calibrator: one which is used when the model is run over simulation time, and a different one for historical time. The //History// tab of the //Variable Information// dialogue is where these links are configured. Binding variables are often base-year variables. Also note that binding variables are //fixed// - their values cannot be set from within a simulator framework - but not all //fixed// variables are binding. See the definition of //fixed// variables. | + | **Binding Variable** - A simulator variable which is linked to two different variables from the calibrator: one which is used when the model is run over simulation time, and a different one for historical time.
