SF298 package giving undefined control sequence error

Question

I am trying to use the SF298 package for latex and it gives an undefined control sequence error. The error is as follows:

! Undefined control sequence.
\ExecuteOptions ...eserved@a \CurrentOption \@nil
l.104 \ExecuteOptions{config,nofloatlongboxes}

The test latex file I am using is as follows:

\documentclass[titlepage]{article}
\usepackage{sf298}

\title{Test Title}
\author{author}

\ReportDate{10--06--1996}
\ReportType{Final}

\begin{document}

  \subsection{Usage}         % subsection 2.1.1

\end{document}

the example can be reduced to

\begin{filecontents}{zz.sty}

  \usepackage{totpages}

\DeclareOption{config}{\def\sf@config{Y}}


\ExecuteOptions{config}
\end{filecontents}

\documentclass[titlepage]{article}
\usepackage{zz}

\stop

On the face of it, seems to be a bug in totpages or one of the packages it loads.

Answer 1

For some reasons, \CurrentOption is defined to expand \@nil and not to empty, as LaTeX expects.

This seems to ba a bug in totpages, which processes options in a personalized way.

The problem may be solved by loading totpages before any package that loads it and to add \def\CurrentOption{} after it.

\documentclass[titlepage]{article}

\usepackage{totpages}
\def\CurrentOption{} % fix bug in totpages

\usepackage{sf298}

In this way, sf298 will not load totpages again and the problem will not show.
