This means that the variable has just one value at a time, and this value is in effect (at least for the moment) throughout the Lisp system. The value remains in effect until you specify a new one. When a new value replaces the old one, no trace of the old value remains in the variable. </p> <p>You specify a value for a symbol with <code>setq</code>. For example, </p> <div class="example"> <pre class="example">(setq x '(a b)) -</pre> -</div> <p>gives the variable <code>x</code> the value <code>(a b)</code>. Note that <code>setq</code> is a special form (see <a href="special-forms">Special Forms</a>); it does not evaluate its first argument, the name of the variable, but it does evaluate the second argument, the new value. </p> <p>Once the variable has a value, you can refer to it by using the symbol itself as an expression. Thus, </p> <div class="example"> <pre class="example">x ⇒ (a b) -</pre> -</div> <p>assuming the <code>setq</code> form shown above has already been executed. </p> <p>If you do set the same variable again, the new value replaces the old one: </p> <div class="example"> <pre class="example">x - ⇒ (a b) -</pre> -<pre class="example">(setq x 4) - ⇒ 4 -</pre> -<pre class="example">x - ⇒ 4 -</pre> -</div><div class="_attribution"> - <p class="_attribution-p"> - Copyright © 1990-1996, 1998-2022 Free Software Foundation, Inc. <br>Licensed under the GNU GPL license.<br> - <a href="https://www.gnu.org/software/emacs/manual/html_node/elisp/Global-Variables.html" class="_attribution-link">https://www.gnu.org/software/emacs/manual/html_node/elisp/Global-Variables.html</a> - </p> -</div> |
