Hash tables have one big disadvantage to me: you have to hsave them. That means, if mIRC crashes you will loose all your data. A small disadvantage is that you cannot change the contents easily unless you have some kind of editor. About speed and INI: if your PC dates from 1990 or so, yes you should use hash tables. But modern PC\'s process INI files fast enough. By the way: INI files are processed in memory! Re: /help /flushini
