First, my documentation had a missing semicolon at the end of
expand(f(a,b)).
The correct file is
-------start ex1.mc--------------------
\documentclass[12pt]{article}
\usepackage{color}
\usepackage{battex}
\begin{document}
\noident We begin by defining the function that squares. We do this with
the Maxima commands
\begin{maxima}
f(x) := x^2;
f(a);
expand(f(a+b));
\end{maxima}
\end{document}
-------end ex1.mc--------------------
Second, because of the difference between end of lines in UNIX and
Windows, my code may misbehave under Windows. I have used it
successfully with NT; I just have my editor save as a UNIX file.
Let me know if it doesn't fix the problem.
