Output Save Set Device Name field

    Use the "Save Set Device Name" field to specify the name of the disk
    or tape onto which the save set will be created.  You can specify
    either a logical device name (such as USER$DISK) or a physical device
    name (such as DKA0). The device must not be allocated by any other
    user and must be a different device than the input device when you
    are saving or restoring a volume.

    Press PF3 to display a box that lists known devices.  Use the arrow
    keys to scroll through the list of devices, and press Return to
    choose a device.  Choosing a device from this box places the list
    entry in the "Save Set Device Name" field.  If you do not want to
    select a device, press PF3 again (or Ctrl/Z) to cancel the box.

    For more information, see "Physical and logical device names" in the
    "Concepts ..." help topic.
