I created a menu, but I can’t find how to add commands to the menu items.

The toolbar buttons on the Menu Editor are used to add top-level menus, menu items in the top-level menus and sub menus.

You can add Menu Handlers to windows so that you can run code when a menu item is selected.

Refer to the Menus topic in the Desktop chapter of User Guide Book 2: User Interface.

It´s clear now, thanx
