1.CDO>  SHOW USED_BY EMPLOYEE_DB

      In this example, because no qualifier is specified, the SHOW

      information includes the names of immediate children of the
      EMPLOYEE_DB database element.

    2.CDO>  SHOW USED_BY /FULL FIELD_A(2)

      In this example, the SHOW USED_BY command with the /FULL
      qualifier displays all children of the FIELD_A(2) field
      element.

    3.CDO>  SHOW USED_BY /FULL /TYPE=(FIELD) EMPLOYEE_REC

      In this example, the SHOW USED_BY command with the /FULL and
      /TYPE qualifiers displays all children of EMPLOYEE_REC that are
      fields.
