+<h2>Syntax</h2>
+
+<dl>
+<dt>(logxor <i>expr1</i> ... )</dt>
+<dd>exprN - an integer expression<br>
+returns - the result of the eXclusive OR operation</dd>
+</dl>
+
+<h2>Description</h2>
+
+<p>The 'logxor' function returns the logical bitwise 'exclusive-or' of the
+list of expressions. If there is only one argument, it is returned
+unaltered. If there are two or more arguments, the 'logxor' function
+performs the 'exclusive-or' successively applying the bitwise operation.</p>
+
+<h2>Examples</h2>
+
+<pre class="example">
+(logxor 0 0)                  <font color="#008844">; returns 0</font>
+(logxor 0 1)                  <font color="#008844">; returns 1</font>
+(logxor 1 0)                  <font color="#008844">; returns 1</font>
+(logxor 1 1)                  <font color="#008844">; returns 0</font>
+
+(logxor #b0011 #b0101)        <font color="#008844">; returns 6</font>
+(logxor 255 #xF0)             <font color="#008844">; returns 15</font>
+(logxor 255 #x0F)             <font color="#008844">; returns 240</font>
+(logxor 255 (logxor 255 99))  <font color="#008844">; returns 99</font>
+</pre>

+<p><b>Note:</b> XLISP does not check when read-macro expansions like '#x0FF'
+are out of bounds. It gives no error message and will just truncate the
+number to the low-order bits that it can deal with [usually 32 bits or 8 hex
+digits].</p>
