>&#13;    When binary SQL data is converted to character C data, each byte
    (8 bits) of source data is represented as two ASCII characters.
    These characters are the ASCII character representation of the
    number in its hexadecimal form. For example, a binary 00000001 is
    converted to <TT
CLASS="literal"
>"01"</TT
> and a binary 11111111 is
    converted to <TT
CLASS="literal"
