       /DESTINATION=device-name:[directory-name]

    Specifies the location where the utility is to place all the
    files that the user indicates are to be retrieved. If the device
    name is not provided, the default is the user's default device.
    If the directory name is omitted, or the /DESTINATION= qualifier
    is not specified, the default is the user's default directory.
    The EXTRACT FILE operation ignores the PCSI$DESTINATION logical
    name whether or not you use the /DESTINATION qualifier.
