<h2>Syntax</h2>
<dl>
<dt>(upper-case-p <i>char</i>)</dt>
<dd><i>char</i> - a character expression<br>
returns - <a href="t.htm"> T </a> if the character
is upper case, <a href="nil.htm">NIL</a> otherwise</dd>
</dl>
<h2>Description</h2>
<p>The 'upper-case-p' predicate function checks if the 'char' expression is
an upper case character. If 'char' is upper case a
<a href="t.htm"> T </a> is returned, otherwise a
<a href="nil.htm">NIL</a> is returned. Upper case characters are
'A' [<a href="../misc/ascii-table.htm">ASCII</a> decimal <nobr>value
65]</nobr> through 'Z' [<a href="../misc/ascii-table.htm">ASCII</a>
decimal <nobr>value 90].</nobr></p>
<h2>Examples</h2>
<pre class="example">
(upper-case-p #\A) <font color="#008844">; returns T</font>
(upper-case-p #\a) <font color="#008844">; returns NIL</font>
(upper-case-p #\1) <font color="#008844">; returns NIL</font>
(upper-case-p #\[) <font color="#008844">; returns NIL</font>
</pre>
