LINGO groups commands under the following five menus:

The File menu contains commands that primarily deal with handling input and output. The Edit menu contains commands for editing the document in the current window. The Solver menu contains commands to solve a model and generate solution reports. The Window menu has commands that deal with the mechanics of handling multiple windows. The Help menu provides access to LINGO's online help facility.

In addition, the Mac has a Lingo menu.  This menu is referred to as the application menu, and is a standard feature of Mac applications.  The application menu typically contains commands to set preferences/options, the application's about box, and the quit command.
