[tex-live] Nested macro resetting problem

[Zdenek Wagner]

Hi Geoffrey,
the easiest way is probably making use of grouping. Try the following
file, it shows different aspects. Notice that the macros must be
\protect'ed in moving arguments.

\documentclass{book}
\def\newabbr#1#2{\expandafter\def\csname #1\endcsname
    {#2 (#1)\expandafter\def\csname #1\endcsname{#1}}}

\newabbr{TUG}{\TeX\ Users Group}
\begin{document}
\tableofcontents
\begin{chapter}{The first chapter}
\TUG

\TUG
\end{chapter}

\begin{chapter}{Another chapter}
\TUG

\TUG
\end{chapter}

\begin{chapter}{Another chapter on \protect \TUG}
\TUG

\TUG
\end{chapter}

\begin{chapter}[The Last chapter]{\protect\TUG}
\TUG

\TUG
\end{chapter}

\begin{chapter}{\protect\TUG\ again}
\TUG

\TUG
\end{chapter}

\begin{chapter}*{Do not put me into toc}
\TUG

\TUG
\end{chapter}
\end{document}
