$ KCAP/TRACK /PERMANENT
                /NOPERMANENT  (default)

   Used to specify that the screen-saving (on AXP) or terminal-logging
   (on AXP or VAX) cannot be shut off for the terminal concerned.

   Example: $ KCAP/TRACK/PERMANENT

   Also applies to terminal-logging on both VAX and AXP. E.g.

     KCAP> TRACK=PERMANENT.LOG /PERMANENT

   The PERMANENT qualifier disallows turning off screen-saving with the
   NOTRACK command. If there is a log file for the screen-saving,
   then the logging cannot be turned off if /PERMANENT is used.

   A permanent screen-saver only goes away when the terminal itself goes
   away (for LTAs etc which are deleted when the user logs off) or when
   the system is shut down (for permanent terminals such as TTAs, etc.).

   The /PERMANENT qualifier should be used with EXTREME CAUTION with
   logging on direct-connect terminal such as TTA's, TXA's or OPA's
   since with these terminals the log file will just continue to grow
   and can't be turned off without rebooting the system.

   /PERMANENT is mainly intended for security use on such things as
   dial-up lines, where a log file of the terminal output is desired
   and the system manager doesn't want the user to be able to stop
   the logging by doing a NOTRACK command.
