+
+<dl>
+<dt>(<b>char=</b> <i>char1 charN</i> ... )</dt>
+<dd><i>char1</i> - a character expression<br>
+<i>charN</i> - character expression[s] to compare<br>
+returns - <a href="t.htm">&nbsp;T&nbsp;</a>
+if the characters are of the same
+<a href="../misc/ascii-table.htm">ASCII</a> value,

+
+<h2>Description</h2>
+
+<p>The 'char=' function tests if all the character arguments are equivalent.
+<nobr><a href="t.htm">&nbsp;T&nbsp;</a> is</nobr> returned if the arguments
+are of the same <a href="../misc/ascii-table.htm">ASCII</a> value,
+<a href="nil.htm">NIL</a> otherwise. <nobr>In the</nobr> case of two
+arguments, this has the effect of testing if 'char1' is equal to 'char2'.
+This test is case sensitive, the character '#\a' is different and of greater
+<a href="../misc/ascii-table.htm">ASCII</a> value than the <nobr>character
+'#\A'</nobr>.</p>
+
+<h2>Examples</h2>
+
+<pre class="example">
+(char= #\a #\b) =&gt; NIL
+(char= #\b #\a) =&gt; NIL
+(char= #\a #\b #\c) =&gt; NIL
+(char= #\a #\a) =&gt; T
+(char= #\a #\a #\a) =&gt; T
+(char= #\a #\a #\b) =&gt; NIL
+(char= #\A #\a) =&gt; NIL
+(char= #\a #\A) =&gt; NIL
