<h2>PROOFS-CO</h2>the proofs character output channel
<pre>Major Section:  <a href="PROGRAMMING.html">PROGRAMMING</a>
</pre><p>

<code>Proofs-co</code> is an <code><a href="LD.html">ld</a></code> special (see <a href="LD.html">ld</a>).  The accessor is
<code>(proofs-co state)</code> and the updater is <code>(set-proofs-co val state)</code>.
<code>Proofs-co</code> must be an open character output channel.  It is to this
channel that <code><a href="DEFUN.html">defun</a></code>, <code><a href="DEFTHM.html">defthm</a></code>, and the other event <a href="COMMAND.html">command</a>s print their
commentary.
<p>
``Proofs-co'' stands for ``proofs character output.'' The initial
value of <code>proofs-co</code> is the same as the value of <code><a href="_star_STANDARD-CO_star_.html">*standard-co*</a></code>
(see <a href="_star_STANDARD-CO_star_.html">*standard-co*</a>).
