Use the SET ABORT command to ensure that execution of a series of DMU
  commands aborts when one of the commands causes a DMU or CDD error.

  If you specify SET ABORT, DMU stops processing a command file as soon
  as one of the commands causes a DMU or CDD error.

  Use the SET NOABORT command to ensure that  execution  of  a  command
  file  of  DMU  commands  continues  to completion, despite CDD or DMU
  errors.

  SET NOABORT is the default.

  Command Syntax:

      SET [NO]ABORT
