Yeah, the topic explains it pretty well. Since there is no official ini format for every file I'd like to know how exactly Autoit is handling it to imitate it for my or espacially the _IniRead(Section(Names)|ToArray) functions which most likely use RegExp (or should use RegExp if it wouldn't fail for _IniReadSectionFromString; see the thread for more information). That's why I'm requesting the ini syntax AutoIt uses in the first place; the best would be as RegExp but this is not that important.
