/CONVERT
       /NOCONVERT

    Converts ODS-5 file names to ODS-2 file names. To preserve the
    output volume as ODS-2, you must also use the /NOINIT qualifier.

    Be aware that all ODS-5 file attributes are lost if you convert
    from an ODS-5 file name to an ODS-2 file name.

    You can also use the /NOCONVERT qualifier.
