[id] = CreateMenu(id, table)
Menutag in the @DISPLAY preprocessor command or in the CreateDisplay() call.
You have to pass an identifier for the new menu strip or Nil. If you
CreateMenu() will return a handle to the new menu strip
which you can then use to refer to this menu strip.
You also need to pass a table containing the actual menu tree definition to this function. Menus are defined as a tree structure that is composed of a master table that contains various subtables. See MENU for a detailed description of menu tree tables.
This command is also available from the preprocessor: Use @MENU to create menu strips at startup time!
