<P>
Index ranges are <em>not</em> allowed on scalars, matrices or tensors, but
subsets of vectors or string variables may be eliminated by including an
index range. For example:</P>
<P>
<CODE><font color="blue">DESTROY X[5:25:5] Y[IDX] S[1:5] T[2][1:10]</font></CODE></P>
<P>
will eliminate elements <CODE>5, 10, 15,</CODE> and <CODE>25</CODE> from
vector <CODE>X</CODE>. If <CODE>IDX</CODE> is a vector, then
<CODE>Y[IDX[1]]</CODE>, <CODE>Y[IDX[2]]</CODE>,
… <CODE>Y[IDX[#]]</CODE> will be eliminated. If
<CODE>S</CODE> is a string variable, characters <CODE>1</CODE> through
<CODE>5</CODE> will be eliminated. If <CODE>T</CODE> is a string array
variable, then characters <CODE>2</CODE> through <CODE>10</CODE> of string
<CODE>2</CODE> will be eliminated.</P>
