Я использую этот файл .Cls и команду, используя 7zip для извлечения конкретного файла из zip.
Мой единственный файл извлекается, как только мне нужно добавить оператор if в se, если мой файл был найден такчто я могу выйти из подпрограммы
можно ли изменить этот кусок кода, добавив собственный код

, поэтому сейчас я пытаюсь получить статус из вывода, используя оператор if для se, если 41_gfx7.rom был найден для того, чтобы я мог выйти из сканирования или подпрограммы, так как нет необходимости сканировать дальше.
или, может быть, если вы можете помочь добавить лучшую, она будет хороша, как только найдена строка, выйдите из подпрограммы
