Re: Макросы
Хаю ду ю ду -=BETA TESTER=-?
Смотрю и вижу, как ты печатаешь умные вещи и дай-ка, думаю,
тоже что-нибудь напечатаю:
BT> Нужно в программе реализовать макросы, посоветуйте компонент.
Например:
1) Компонент TScript Язык скрипта - подмножество Дельфи-паскаля.
2) Innerfuse Pascal Script 2.78
3) MSScriptControl.ScriptControl
Да много всякого - спроси у яндекса
