/* mrds_scanner_tables.incl.pl1 

   These are the tables that drive the scanner for MRDS selection expression 
   parsing.

   Originally created 08-04-85 J. Hergert


 The following declaration is used by the scanner to type the token it is 
 about to parse. The first character determines what the token could be.

 The codes in the following declaration are deciphered as follows:
 Any code >  0 is a token type, indicating the type of token we will try 
 to find. Codes less than 0 are negated keyword encode values. These token 
 types are simple one character tokens and no further searching need be 
 done when we find one.

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. .
