yes, ASCII(26) is control-Z, or on windows, as you already said: EOF, or end-of-file... i dont think it's a bug, because mIRC naturally loads everything until the literal "end of file" :P a simple way around it would probably be to put $+ $chr(26) $+ instead of the actual char into the source, if that (for one or another reason) is not good enough, a different char is needed
