<DT><B> Usage </B><DD>
<P><CODE>Array_Type shift (Array_Type A, Int_Type n)</CODE></P>
<DT><B> Description </B><DD>
<P>The <CODE>shift</CODE> function shifts the elements of an array by a specified amount
and returns the result.  If <CODE>n</CODE> is positive, the ith element of the array
will be shifted to the position <CODE>i-n</CODE> of the array.  Elements for 
which <CODE>i-n</CODE> is less than 0 will be moved to the end of the array.</P>

<P>It many ways <CODE>rotate</CODE> would be a better name for this function.</P>
