<P>
The contour levels are automatically stored in a vector named
<CODE><font color="orange">CCONT</font></CODE>. If the
<CODE>\COORDINATES</CODE> qualifier is used, the
<i>x</i> and <i>y</i> coordinates of each contour level are stored in
matrices named <CODE><font color="orange">XCNT</font></CODE> and
<CODE><font color="orange">YCNT</font></CODE>. The number of points stored
for each level is the first element of each column. For example,
<code><font color="orange">XCNT</font>[1,nc] (=n1)</code> is the number of
points making up contour number <CODE>nc</CODE>, while
<code><font color="orange">XCNT</font>[2:n1+1,nc]</code> and
<code><font color="orange">YCNT</font>[2:n1+1,nc]</code> would contain the
<i>x</i> and <i>y</i> coordinates of the <CODE>nc</CODE><sup>th</sup> contour
level. These vectors are then available to the user for plotting and/or
manipulation. Each time the <CODE>CONTOUR</CODE>
command is entered, these vectors are emptied and replaced, so if you wish
to keep them, they should be renamed or copied into other vectors.</P>
