|
Мне иногда страшно представить сколько лишнего(мусорного) кода содержит ассемблерный код, скомпилированный из чистого, без лишних переменных и функций скрипта тк думаю что компилятору инно далеко до например дельфи 2010 
вот только сжатие. Константы все наместе, тк если будет ошибка, то поймёшь что означает по имени константы

UPD
Shegorat, пардон, не увидел  |
Не могли бы Вы, пожалуйста, подсказать, как в этом коде отделить функцию распаковки и запаковки. То есть, мне нужна только функция распаковки. Это надо, так сказать бо большому счёту для истетики 
чтобы в коде не было ничего лишнего. И возможно ли добавить к нему кнопку "Отмена"?
