From Oracle8 complete reference:

CHAR(size) Fixed-length character data, "size" character long. Maximum size

                is 2000. Default 1 byte. Padded on the right with blanks to
full
                length of size.

VARCHAR2(size) Variable length character string having a maximum of "size" bytes

                (up to 4000).

VARCHAR(size) Same as varchar2. Use varchar2, since varchar's usage may change

                in future version of Oracle.

This is my reference. Where you find that data are stored in the same way (size then data and not only data for char)? This is not polemic, just a new information for me too.

Thanks,
Marco
