The result is the variable’s value, if it has one. If the symbol has no value as a variable, the Lisp interpreter signals an error. For more information on the use of variables, see <a href="variables">Variables</a>. </p> <p>In the following example, we set the value of a symbol with <code>setq</code>. Then we evaluate the symbol, and get back the value that <code>setq</code> stored. </p> <div class="example"> <pre class="example">(setq a 123) - ⇒ 123 -</pre> -<pre class="example">(eval 'a) - ⇒ 123 -</pre> -<pre class="example">a - ⇒ 123 -</pre> -</div> <p>The symbols <code>nil</code> and <code>t</code> are treated specially, so that the value of <code>nil</code> is always <code>nil</code>, and the value of <code>t</code> is always <code>t</code>; you cannot set or bind them to any other values. Thus, these two symbols act like self-evaluating forms, even though <code>eval</code> treats them like any other symbol. A symbol whose name starts with ‘<samp>:</samp>’ also self-evaluates in the same way; likewise, its value ordinarily cannot be changed.
