The Command Window box on the Interface tab:

is used to customize the configuration of LINGO's command window.

LINGO's command window can be opened using the Window|Command Window command. This gives the user a command-line interface to LINGO. This interface is identical to ones used by LINGO on platforms other than Windows. The command window is also useful for testing LINGO command scripts. For more information on the commands available under LINGO's command-line interface, refer to Command-line Commands.
