      <td>returns an array of shape <apll>L</apll> whose items are taken from <apll>R</apll> in row major order, repeated as necessary.</td>

<tr>
  <td><apll>L</apll> is a scalar or vector of non-negative integers, and <apll>R</apll> is an arbitrary array.</td>
</tr>
<tr>
  <td>If the right argument is empty, the result consists of <apll>×/⍴L</apll> copies of the fill item of <apll>R</apll>.
</tr>

<p>For example, in origin-1</p>
 
<apll>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2 3⍴⍳6<br />
&nbsp;1 2 3<br />
&nbsp;4 5 6<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2 3⍴⍳0<br />
&nbsp;0 0 0<br />
&nbsp;0 0 0<br /></apll>
 
<p>The idea for the latter enhancement was taken from Dyalog APL.</p>
