<P>
Indices can be used on any function. For example,
if <code>x</code> and <code>y</code> are vectors of length <CODE>10</CODE>,
then <code>sin(x+y)</code> is also a vector of length <CODE>10</CODE>, and
an index can be used, such as <code>sin(x+y)[3]</code>.</p>
<p>
The special index characters <CODE>#</CODE> and <CODE>*</CODE> <em>cannot</em> be used in indices on
functions.</P>
