The following example for the Oracle CODASYL DBMS database
       PARTS_DB connects an employee named Hill to a part LA36 in the
       RESPONSIBLE_FOR set. The ROLLBACK statement undoes the change:

       DTR> FIND E IN EMPLOYEES WITH EMP_LAST_NAME = "HILL"
       DTR> SELECT 1
       DTR> FOR P IN PART WITH PART_DESC = "LA36"
       CON>     CONNECT P TO E.RESPONSIBLE_FOR
       DTR>  ROLLBACK
       DTR>
