вызвать системную команду Windows через fortran без отображения окна оболочки и вывести результат во внешний файл

Вы также разместили это на странице Форум Intel и пользователь Пол Кертис ответил примером того, как получить MAC-адрес напрямую с помощью Windows API.

Поскольку StackOverflow предпочитает ответы, а не просто ссылки, я включил приведенный ниже код.
