I have a doubt the concept of defining structures.In htdp chapter 6&nbsp; its given as<br><br>
A <small>S</small><small>T</small><small>R</small><small>U</small><small>C</small><small>T</small><small>U</small><small>R</small><small>E</small> <small>D</small><small>E</small><small>F</small><small>I</small><small>N</small><small>I</small><small>T</small><small>I</small><small>O</small><small>N</small> 
<a name="node_idx_432"></a>is, as the term says, a new form of
definition. Here is DrScheme&#39;s definition of <code class="scheme"><span class="variable">posn: i have modified the example here<br><br></span></code><pre class="scheme">(<span class="keyword">define-struct</span> <span class="variable">entry</span> (<span class="variable">name</span> <span class="variable">zip</span> <span class="variable">phone</span>))<br>
<br>Now a few lines later it says <br><br><br>If we give the structure a name,<br><br>(<span class="keyword">define</span> <span class="variable">phonebook</span> (<span class="builtin">make-entry</span> <span class="keyword">&#39;</span><span class="variable">PeterLee</span> <span class="selfeval">15270</span> <span class="keyword">&#39;</span><span class="variable">606-7771</span>))<br>
</pre>Now my question here is&nbsp; phonebook the name of the structure&nbsp; or it is a structure of type entry?<br><br><br>Aditya<br>
