the following example contrasts legal with illegal array creation and
assignment</p>
<pre><code> real y[5];
 int x[5];
 
 x = rep_array(1,5);     // ok
 y = rep_array(1.0,5);   // ok
 
 x = rep_array(1.0,5);   // illegal
 y = rep_array(1,5);     // illegal
 
 x = y;                  // illegal
 y = x;                  // illegal</code></pre>
<p>If the value being repeated <code>v</code> is a vector (i.e., <code>T</code> is <code>vector</code>),
then <code>rep_a
