%D Because some characters have a special meaning, we provide
%D shortcuts to their character representation.

\chardef\^=\circumflexasciicode
\chardef\_=\underscoreasciicode % but way too wide in lm, so ... until that's fixed:
\chardef\&=\ampersandasciicode
\chardef\%=\commentasciicode
\chardef\#=\hashasciicode
\chardef\$=\dollarasciicode
\chardef\{=\leftbraceasciicode
\chardef\}=\rightbraceasciicode
\chardef\\=\backslashasciicode

%def\_{\leavevmode     \kern.06em \vbox{\hrule width.3em}}
\def\_{\dontleavehmode \kern.06em \vbox{\hrule width.3em}}

%D From now on we can use the protection mechanisms.

\def\unprotect {\pushcatcodetable\setcatcodetable\prtcatcodes}
\def\protect   {\popcatcodetable}
