This chapter presents two listings:
\begin{itemize}
\item ``Accessors'', whose names start with \verb|$| and which serve
  to retrieve the values of internal variables or constants.  These do
  not take any arguments.
\item Functions proper. In almost all cases these require at least one
  argument, and even if no argument is required an empty ``argument
  slot'' \texttt{()} is mandatory.
\end{itemize}
