<P>
 The <CODE>DESTROY</CODE> command eliminates subsets
 of vectors or string variables, or it destroys scalars, matrices and tensors.</p>
<P>
 When scalars, matrices or tensors are entered, they are completely destroyed.
 Index ranges are not allowed on scalars, matrices or tensors. These variables
 are simply eliminated.  By default, variable names are not constructed or
 expanded.</P>
<P>
 If vectors are entered with no index ranges, they are entirely eliminated.
 Subsets of vectors or of string variables may be eliminated by including
 an index range.</P>
