It doesn't return anything, but that's my point.. even though the file doesn't exist mIRC doesn't raise an error.

/noop is a command that does nothing with the return value of the identifier. It's for identifiers that you don't need to do anything with the out, such as $findfile:

Code:
//noop $findfile($mircdir,*,0,echo -s $1-)


$ini() will work with text files too.
