12       Pstat  interprets  the  contents  of certain system tables.  If file is
13       given, the  tables  are  sought  there,  otherwise  in  /dev/mem.   The
14       required namelist is taken from /unix.  Options are
16       -a    Under  -p,  describe  all  process  slots rather than just active
17             ones.
