+<h2>Syntax</h2>

+
+<h2>Description</h2>
+
+<p>The T system constant is built into XLISP. T represents 'true',
+as oppossed to <nobr><a href="nil.htm">NIL</a> ,</nobr>
+representing 'false'.</p>
+
+<h2>Examples</h2>
+
+<pre class="example">
+(setq myvar T)                     <font color="#008844">; set MYVAR to True</font>
+(setq myvar 'T)                    <font color="#008844">; T and 'T both evaluate to T</font>
+(if t (print "this will print")    <font color="#008844">; if, then, else</font>
+      (print "this won't print"))
+</pre>
+
+<p><b>Note:</b> Be careful with the T value. It is possible to do a
+<a href="setq.htm">setq</a> on T and set it to other values like
+<a href="nil.htm">NIL</a>. Some operations will still return
+proper T or <a href="nil.htm">NIL</a> values, but the system
+will be in a bad state.</p>
