/* DESCRIPTION:

   This  structure  is  allocated  in  the  mdbm_rm_db_info.incl.pl1
   static  area,  once per attribute used in a relation in a readied
   file. it is pointed to by the mdbm_rm_attr_info.incl.pl1, and may
   point  to  mdbm_rm_ck_and_group.incl.pl1  if  a  "-check"  option
   boolean expression was declared for this domain. it contains  the
   descriptor  for  this domain data type, and other resultant model
   information.


   HISTORY:

   81-05-06  Rickie  E.  Brinegar:  Modified  ck_proc,  encode_proc,
   decode_proc to be entry variables instead of entry pointers. This
   allows these programs to be written in languages other than pl1.

   81-05-28 Jim Gray : removed unused procedure points,  and  unused
   check  stack  structure  elements.  Also made the descriptors bit
   (36) in this structure, rather than pointers to  the  descriptors
   elsewhere.  Also  removed un-needed redundant assign_ parameters,
   that are actually available in the descriptors.

Historical Background

This edition of the Multics software materials and documentation is provided and donated
to Massachusetts Institute of Technology by Group Bull including Bull HN Information Systems Inc. 
as a contribution to computer science knowledge.  
This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology,
Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell Bull Inc., Groupe Bull
and Bull HN Information Systems Inc. to the development of this operating system. 
Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970),
renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership
of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture for 
managing computer hardware properly and for executing programs. Many subsequent operating systems 
incorporated Multics principles.
Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., 
as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. .
