HELPLIB.HLB  —  Ext File Specs, Using  Working in Mixed Environments
    If working in an environment which contains both OpenVMS Alpha
    and OpenVMS VAX systems, it becomes more important to know on
    which type of volume files are being created and on which type of
    volume your default directory resides.

    When accessing an ODS-5 volume, you need to set the parse style
    to EXTENDED to accept and display extended file specifications.
    The default setting is TRADITIONAL. To set the parse style, enter
    the command:

    $ SET PROCESS/PARSE_STYLE=EXTENDED

    When working in a mixed environment of OpenVMS VAX and OpenVMS
    Alpha, it is important for users to realize upon which system
    they are working. OpenVMS 7.2 and later allows VAX systems to
    mount ODS-5 volumes; however users on OpenVMS VAX systems can
    access only files with ODS-2-compliant file names.

    When working in a mixed environment of ODS-2 and ODS-5 volumes,
    keep in mind the restrictions of ODS-2 file names when creating
    files on ODS-5 volumes. If a file is created with special
    characters on an ODS-5 volume, the file must be given an ODS-2
    compliant name if it is copied to an ODS-2 volume.
