<body text=#000000 bgcolor="#FFFFFF">
<h2>LD-VERBOSE</h2>determines whether <code><a href="LD.html">ld</a></code> prints ``ACL2 Loading ...''
<pre>Major Section: <a href="MISCELLANEOUS.html">MISCELLANEOUS</a>
</pre><p>
<code>Ld-verbose</code> is an <code><a href="LD.html">ld</a></code> special (see <a href="LD.html">ld</a>). The accessor is
<code>(ld-verbose state)</code> and the updater is <code>(set-ld-verbose val state)</code>.
<code>Ld-verbose</code> must be <code>t</code>, <code>nil</code> or a string or <code><a href="CONSP.html">consp</a></code> suitable for <code><a href="FMT.html">fmt</a></code>
printing via the <code>~@</code> command. The initial value of <code>ld-verbose</code> is a
<code><a href="FMT.html">fmt</a></code> message that prints the ACL2 version number, <code><a href="LD.html">ld</a></code> level and
connected book directory.
<p>
Before processing the forms in <code><a href="STANDARD-OI.html">standard-oi</a></code>, <code><a href="LD.html">ld</a></code> may print a header.
The printing of this header is controlled by <code>ld-verbose</code>. If
<code>ld-verbose</code> is <code>nil</code>, no header is printed. If it is <code>t</code>, <code><a href="LD.html">ld</a></code> prints the
message
<pre>
ACL2 loading <file>
</pre>
where <code><file></code> is the input channel supplied to <code><a href="LD.html">ld</a></code>. A similar
message is printed when <code><a href="LD.html">ld</a></code> completes. If <code>ld-verbose</code> is neither <code>t</code>
nor <code>nil</code> then it is presumably a header and is printed with the <code>~@</code>
<code><a href="FMT.html">fmt</a></code> directive before <code><a href="LD.html">ld</a></code> begins to read and process forms. In this
case the <code>~@</code> <code><a href="FMT.html">fmt</a></code> directive is interpreted in an environment in which
<code>#\v</code> is the ACL2 version string, <code>#\l</code> is the level of the current
recursion in <code><a href="LD.html">ld</a></code> and/or <code><a href="WORMHOLE.html">wormhole</a></code>, and <code>#\c</code> is the connected book
directory <code>(cbd)</code>.
