SUBS (SUBSYSTEM) -- Set or display subsystem attributes.
usage:  SUBS object [subs_name] [-DATA] [-MGR] [-L] [-UP | -DOWN] [-BR]


FORMAT

  SUBS object [subs_name] [options]


  SUBS is used to set or show protected subsystem attributes.
  When setting subsystem attributes, you must be running in that
  subsystem.  Type HELP ENSUBS for details on entering a subsystem.



ARGUMENTS

  object
  (required)       Specify pathname of an object.  The function of the
                   object (either a protected file or a managing program)
                   is determined by options described below.

  subs_name
  (optional)       Specify name of a subsystem.  The Shell will search
                   the directory /SYS/SUBSYS for the specified subsystem.
                   If this argument is specified, the attributes of the
                   named subsystem will be set as directed by the options
                   described below.
                   Default if omitted: display attributes of 'object'

OPTIONS

    -DATA          Set or display the name of the subsystem which
                   manages 'object'.

    -MGR           Set or display the name of the subsystem for
                   which 'object' is a manager. 'Object' must be
                   a program.

    -UP            Increase the privilege level of a process
                   running in a subsystem so that it can directly
                   access the objects it owns.

    -DOWN          Decrease the privilege level of a process;
                   opposite of '-UP'.

    -L             List subsytem attributes of object.  This is
                   the default action if 'subs_name' is not specified.

    -BR            Display only the name of the subsystem.  Not
                   valid if attributes are being set.
