% mods : \c@ changed to \@c@  (--bg 11/30/92)
%        ^^d9 \lccode was wrong, should be ^^f9 12/09/94
%        ^^a3 sanitized (--bg 03/06/95)
%        \'u & \'U added --bg 05/02/95 (pointed by F. Poirion)  
% \uccodes added 
\input compatible 
% Michael J. Ferguson 
% The codes used here convert the TeX \' ... accent sequences
% into the equivalent ISO - Latin 1 values and also  provide
% their inverses. 
% The ISO -Latin 1 code set is almost identical to the
% Digital (DEC) Multinational Character set.
