%  This file contains definitions for math symbols and operators 
%  --- normally found in the fonts MSAM* and MSBM* ---
%  using LucidaNewMath fonts from Y&Y in Adobe Type 1 format.

%  It is assumed here that `lcdplain.tex' or `lcdlatex.tex' have been loaded
%  --- while `amstex.tex' and `amssym.def' are not required ---
%  this defines things like \arfam which are needed here.

% We make @ signs act like letters, temporarily, to avoid conflict
% between user names and internal control sequences of plain format.

\chardef\atcode=\catcode`\@	% save catcode of at sign
\catcode`\@=11			% make at a letter

% Protect against style files that make quotedbl `active'

\chardef\dblcode=\catcode`\"	% save catcode of quotedbl
\catcode`\"=12			% make quotedbl what it should be
