The next four digits are '0033' showing that the datafield is of 33 characters in length. '000289' shows that the datafield begins two-hundred eighty-nine characters after the base address of the data, The digit '1' shows that this datafield belongs to the second segment of the record; datafield belonging to the primary segment will carry the segment identifier '0'. The final digit, '0', indicates that this is first occurrence of a datafield tagged 300 in segment 1.
