/*
   Modified in July 1977 by R.J.C. Kissel to handle new data types.  When any_to_any_ is
   updated to handle all data types, all references to probe_assign_ should be changed to references
   to assign_ and probe_assign_ and probe_convert_ should be deleted.
   Modified 11 Apr 79 JRDavis for proper handling of unaligned dec  -use data_type_info_
   Modified 20 June 79 JRDavis to use assign_$computational_ instead of probe_assign_
   Modified 2 Feb 84 JRGray to use generic_decimal types and to remove call to numeric_to_ascii_

  1) change(86-09-05,JMAthane), approve(86-09-05,MCR7525),
     audit(86-09-11,Martinson), install(86-11-12,MR12.0-1212):
     Added runtime_symbol_info_$subrange entry which was missing.  Added
     has_dimensions and has_subrange_limits fields in type_info record.
     Structure version numbers have not been changed since this change does not
     affect existing programs.
                                                   END HISTORY COMMENTS */

/* Written June 83 JMAthane Grenoble University */

/* This set of entries return information about both old (fixed format)
   and new (variable format designed for PASCAL) symbol tables */


/* The include segment runtime_symbol_info_.incl.pl1 contains declarations
          of these entries and of the structures filled by them.  */
/* Changed to use include file declarations 09/02/83 S. Herbst */
/* Added version strings to structures, status codes to entries using them 10/05/83 S. Herbst */
/* Added subrange entry, and filling of new fields in type_info
(size_is_encoded, has_subrange_limits and has_dimensions)	JMAthane 08/31/84 */

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. .
