And you should at least show that you've taken some effort to solve the problem yourself before posting a question to a forum. You not even got the syntax right??? It should read "vector<T>" instead of "vector(T)". Please get a book and read it through. Stop bugging people on this mailing list. (I haven't taken my sedatives today...) -- Claudio
