I'd say no. According to the grammer, "/* this is */" is the <bracket comment> and what's following is not valid. As soon as a token is found (in this case the first <bracket comment terminator>) it is processed. Therefore the first "*/" ends the bracket comment and the following characters are not part of the comment anymore. Cheers, Udo
