RMS_FILEPROT

   RMS_FILEPROT determines the default file protection for system
   processes such as those that create the error log, operator log,
   and job controller. It also determines default file protection
   for processes created by the job controller (all interactive and
   batch processes).

   Because a process always inherits its default file protection
   from its creator process, RMS_FILEPROT determines default file
   protection only for users who do not execute the DCL command SET
   PROTECTION/DEFAULT in their login command procedures or during
   interactive sessions.

   The protection is expressed as a mask. (See the discussion of
   the $CRMPSC system service in the VSI OpenVMS System Services
   Reference Manual for more information about specifying protection
   masks.) By default, the mask is 64000 (decimal) or FA00
   (hexadecimal), which represents the following protection:
