<h1>single</h1>

<h2>Purpose</h2>

<p>Perform the DEFAULT single tier reduction. This reduces the entire set 
 of nodes that matched a rule phrase.</p>

<h2>Syntax</h2>

<p style="line-height: normal;
			margin-bottom: 14pt;
			margin-top: 14pt;
			x-text-tab-stops: repeat 1in;
			white-space: nowrap;
			font-family: monospace;
			font-size: 10pt;">single()</p>

<h2>Returns</h2>

<h2>Remarks</h2>

<h2>Example</h2>

<p># Since @POST is non-empty, you must explicitly specify reduction.<br>
@POST<br>
 <!--kadov_tag{{<spaces>}}-->&nbsp;<!--kadov_tag{{</spaces>}}-->++G(&quot;nouns&quot;);<br>
 <!--kadov_tag{{<spaces>}}-->&nbsp;<!--kadov_tag{{</spaces>}}-->single(); 
 <!--kadov_tag{{<spaces>}}-->&nbsp;<!--kadov_tag{{</spaces>}}--># NEEDED, 
 or computer will not reduce to _noun.<br>
@RULES<br>
_noun &lt;- computer @@<br>
<br>
# In this case, @POST is empty, so single() occurs by default.<br>
@POST<br>
@RULES<br>
_noun &lt;- sheep @@</p>
