Why would you locate a value without a specific item name? There's no way for mIRC to know what item you're referring to if you don't tell it..
This isn't even an INI specific issue.. Even when you tell mIRC which token you want from a string via $gettok you have to give it an index. Similarly, when you $read lines from a file in order, you also have to provide line numbers. Otherwise, again, there's no way for mIRC to know.
You might want to use /fopen and $fread, which are stateful file handling operations. $fread does not require specifying a line number for this reason. $readini/$read will never behave this way. /writeini doesn't need to, either, since $readini will not.
