VMS Help DCL Tips, Protection  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Volume and file protection is specified as follows:

         (SYSTEM:RWED,OWNER:RWED,GROUP:RWED,WORLD:RWED)

    There are four categories of protection: one for system
    processes, one for the owner of the file, one for other members
    of the owner's group, and one for members of other groups. For
    each category, any combination of four different types of access
    may be specified:

    R    read access
    W    write access
    E    execute access (for execution of images)
    D    delete access

    If you want to deny all access to a category, you must specify
    the category name without a colon, for example:

         /PROTECTION=(OWNER:RWE,GROUP,WORLD)

    For complete information on setting protections, see the OpenVMS
    Guide to System Security.

1 - Example

  $ DIRECTORY/PROTECTION JUNE_REPORT.LIS
  Directory DISK1:[J_BROWN]

   JUNE_REPORT.LIS;1          (RWED,RWED,RE,)

      In this example, the user entered the DIRECTORY/PROTECTION
      command to see what the protection is for the file JUNE_
      REPORT.LIS. Users in the system and owner categories have read,
      write, execute, and delete access, users in the group category
      have read and execute access, and users in the world category
      have no access to this file.
