Are you saying that >my code could stop working when I switch to another compiler? B. Hyatt is on vacation so I will answer this. He is not kidding and your code could break with any other compiler easily. chars are not guaranteed to be signed or unsigned. It is implementation defined. It is safe to declared them unsigned or signed from the beginning. For instance, see: http://www.eskimo.com/~scs/C-faq/q1.1.html Regards, Miguel > >Tord
