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