/ENABLE=(LOAD,PERM)
    /DISABLE=(LOAD,PERM)

    The /ENABLE and /DISABLE qualifiers allow you to disable or
    selectively enable automatic loading and automatic permanence
    for all non-permanent devices. The two qualifiers have these
    meanings:

    Qualifier  Explanation

    /ENABLE    Allows you to selectively enable automatic loading
               permanence. Automatic permanence is ignored if
               automatic loading is disabled. However, you can enable
               automatic loading and disable automatic permanence.
               This allows devices to be configured but does not
               add them to the permanent database. Also, the OpenVMS
               device name cannot be persistent.
    /DISABLE   Allows you to disable device loading on a per-device
               basis.

    Explanations of the keywords LOAD and PERM are in the following
    table:

    KeyworTerm             Explanation

    LOAD  Automatic        Allows the device to be automatically
          loading          configured-that is, the device driver is
                           loaded and an OpenVMS device is created
                           for it.
    PERM  Automatic        Causes the UCM to add the device to the
          permanence       permanent database. Once a device is added
                           to the permanent database, each time it
                           is connected to the system it will have
                           the driver loaded and the device name will
                           always remain the same-that is, it will be
                           persistent.

    By default, automatic loading (LOAD) and automatic permanence
    (PERM) are enabled. Automatic permanence is ignored if automatic
    loading is disabled. However, you can enable automatic loading
    and disable automatic permanence. This allows devices to be
    configured but does not add them to the permanent database. (The
    OpenVMS device name might not be persistent in this case.)
