%  Initializes upper/lowercase lookup tables for DOS code page 437.
%  437 is the original DOS character table. So if your DOS version
%  does not support code pages, use this table. 437 is also the
%  default code page for USA, United Kingdom, and International English.
%  It is the alternate code page for Belgium, Brazil, Finland, France,
%  Germany, Italy, Latin America, Netherlands, Spain, Sweden, and
%  Switzerland.
