  Definition of record REC2 |   Contains field           FLD1
  CDO> ROLLBACK

  %CDO-E-ERRSHOW, error displaying an object
  -CDO-E-NOTFOUND, entity REC2 not found in dictionary

      In this example, a record is defined within a transaction,
      but because the transaction is terminated using the ROLLBACK
      command, the record is not defined.
