Re: indexing puzzle

For anyone interested in producing classical indices locorum, I have
devised a way that seems to work, although it is not that elegant.

The first step is to modify the sort keys by counting the number of digits
in the page number:
thus,
[AuthorText01] for pages 1–9,
[AuthorText02] for pages 10–99, and so on

The next is to insert the command “ \ab” (note the space) when the line
number is a single digit:
thus
391. \ab{}2 but 391.12 in the entry specification {Author+Text+page.line}

For \ab, I have:

\newdimen\digitwidth
\setbox0=\hbox{\tfx\char32}
\digitwidth=\wd0

\def\ab{\tfx\kern-\digitwidth}

The hitch here is that the font size is not context dependent.
