END              Terminate module                                   Directive

  END [expression]

    Marks the end of a module. All statements following this directive are
    ignored.

    The expression argument, if present, indicates the program entry
    point--the address at which the program will begin execution. A
    program may have more than one module, but only one module may define
    an entry point. The module with the defined entry point is called the
    main module.
