<h2>Syntax</h2>
<p><div class="box">
<dl>
<dt>(<b>both-case-p</b> <i>char</i>)</dt>
<dd><i>char</i> - a character expression<br>
returns - <a href="t.htm"> T </a> if the character
is alphabetic, <a href="nil.htm">NIL</a> otherwise</dd>
</dl>
</div></p>
<h2>Description</h2>
<p>The '<nobr>both-case-p</nobr>' predicate function checks if the 'char'
expression evaluates to an alphabetic character. <nobr>If 'char'</nobr>
evaluates to an alphabetic [either an upper or lower case] character
<a href="t.htm"> T </a> is returned, otherwise
<a href="nil.htm">NIL</a> is returned. Note that XLISP is limited to <a
href="../misc/ascii-table.htm">ASCII</a> characters, so there is no way to
find out if an Unicode character is '<nobr>both-case-p</nobr>' if the
<nobr><a href="char-code.htm">char-code</a></nobr> is greater <nobr>than
127</nobr>.</nobr></p>
<h2>Examples</h2>
<pre class="example">
(both-case-p #\A) => T
(both-case-p #\a) => T
(both-case-p #\1) => NIL
(both-case-p #\[) => NIL
</pre>
