[tex-eplain] indexing appendices

[Helmut Jarausch]

Hi,

meanwhile I took a different approach which doesn't suffer from
any problems (I do have an append 'D')

As the result of my previous questions I have defined my
indexing macro '@' as follows

\catcode`\@=\active
\let\RefPageMarkUp=\relax
\newtoks\myreffirstarg
\def @#1|{\myreffirstarg={#1}\myrefoneortwo}
\def \myrefoneortwo{%
     \ifx\RefPageMarkUp\relax
       \edef\temp{\noexpand\sidx{\the\myreffirstarg}}%
     \else
       \edef\temp{\noexpand\sidx[pagemarkup=\RefPageMarkUp]{\the\myreffirstarg}}%
     \fi
     \temp
}

Now at the start of Index D I have
\def\RefPageMarkUp{AppD}

and my TeX-file producing the index contains a definition for each
index like

\def\AppD#1{D#1}

Many thanks for your help. Meanwhile I had a closer look
at Victor Eijkhout's TeX by Topic
which contains many of those tricky details in TeX.


Helmut.
