{393} lines -4 through -2:  The untie and the undef statements were
reversed, as shown:

        untie %db_hash;

                                     # closes it.  Closing DB_FH is implicit.

now reads:

        undef $db_obj;               # removing the last reference to the DB
                                     # closes it.  Closing DB_FH is implicit.
        untie %db_hash
