<h2>Syntax</h2>
<dl>
<dt>(get-key)</dt>
<dd>returns - the decimal ASCII value of the key pressed</dd>
</dl>
<h2>Description</h2>
<p>The 'get-key' function gets a single key stroke from the keyboard [as
opposed to an entire line, as <a href="">read</a> does].</p>
<p><b>Note:</b> In Nyquist, this function is only defined to work on Unix
systems [including Linux and <nobr>Mac OS X]</nobr>. <nobr>On
Windows</nobr> systems, <a href="nil.htm">NIL</a> is returned.</p>
<h2>Examples</h2>
<pre class="example">
(setq mychar (get-key)) <font color="#008844"> ; get a character</font>
</pre>
