In addition to the pull down menu commands, LINGO's features can also be accessed through a command language. For more details on the command language refer to Command-line Commands. A script file that contains LINGO commands may be run using the File|Take Commands command or by entering the TAKE command in LINGO's command window.

In general, you will probably prefer to use the pull down menus and toolbar when using LINGO interactively. The command window interface is primarily provided for users wishing to interactively test command scripts.
