This chapter provides a reference to the various windows of the Time Series Forecasting System. The windows are presented in alphabetical order by name. Each section describes the purpose of the window, how to open it, its controls, fields, and menus. For windows that have their own menus, there is a description of each menu item under the heading "Menu Bar." These windows also have a toolbar with icons that duplicate the more commonly used menu items. Each icon has a screen tip: a brief description that appears when you hover the mouse cursor over the icon. If you don’t see the screen tips, open the SAS Preferences window, under the Options submenu of the Tools menu. Select the View tab and make sure the "Screen tips" check box is checked.
