Important data:
Ultrix 4.0 on a Decstation 5000/200
TeX C Version 2.95
SliTeX Version 2.09 - Release 10 November 86

It seems that it is possible to have the contents of a verbatim
environment make a difference.

The file runoff.tex:

\documentstyle{slides}
\onlyslides{2}
\begin{document}
\blackandwhite{slides}
\end{document}

The file slides.tex:

\begin{slide}{}
\begin{verbatim}
{ % }
\end{verbatim}
\end{slide}

If the onlyslides line above is commented out, everything runs fine.
However, with it there, the following error is produced:

This is TeX, C Version 2.95 (no format preloaded)

SliTeX Version 2.09 - Release 10 November 86

Transcript written on runoff.log.

It appears that the % inside the verbatim environment is acting as a
comment.  I discovered this the hard way because of a short C function
with a printf statement which happened to be in a verbatim
environment.

Is there an easy work-around for this problem?  A hard one?
