Код листинга 1.2 показывает, что он оформлен как полноценная программа на ассемблере. Код программы был сгенерирован компилятором Visual C++ 4.0 , поэтому транслятор MASM может сделать на него загрузочный модуль дополнительного редактирования.Таким образом, имея исходный файл Windows-приложения на языке С/С++, можно получить текст на языке ассемблера
