    CMS> RETRIEVE ARCHIVE/GENERATION=2A3 SAMPLE.CMS_ARCHIVE
    %CMS-S-RETRIEVED, generation 2A3 of element
    DISKX:[PROJECT.CMSLIB]SAMPLE.PAS retrieved from
    DISKX:[WORK]SAMPLE.CMS_ARCHIVE;1

      This command retrieves generation 2A3 from the file SAMPLE.CMS_
      ARCHIVE in your default directory. CMS names generation 2A3
      to its original element name SAMPLE.PAS and places it in your
      default directory.
