The Input screen is used to set up model inputs (Constants and Lookups), either prior to a simulation or during a game (see Game Control, above). If necessary, you might need additional Input screens to accommodate large numbers of inputs. Input controls include text editing boxes (MODVAR) and sliders (SLIDEVAR) which modify a variable's value, and radio buttons (RADIOVAR) and list boxes (LISTVAR) which force the user to choose one option from a set of options. Lookup input controls (MODTABLE) are used for modifying lookups. Checkboxes (SWITCHVAR) toggle between two values (often for ON or OFF). The Input screen also contains the Simulate button (or Forward button in a Game Control). Clicking on this sets the simulation in progress and will move the user to the Output screens.
