I thought it was unlikely to be strictly legal C and wasn't sure whether some compilers would accept it, so ran a couple of tests earlier today. Other compilers may accept it but those are the two I have immediately available. On the face of it, a compiler should throw an error since, unlike "" (the empty string) char is a fixed size variable, which makes supplying an empty literal a meaningless expression. Martin
