%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
\chardef \| = \barasciicode

%def\_{\leavevmode     \kern.06em \vbox{\hrule width.3em}}
\def\_{\dontleavehmode \kern.06em \vbox{\hrule width.3em}} % this will become a \chardef

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

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