<h2>INTERN$</h2>create a new symbol in a given package
<pre>Major Section: <a href="PROGRAMMING.html">PROGRAMMING</a>
</pre><p>
<code>Intern$</code> is a macro that behaves the same as the macro <code><a href="INTERN.html">intern</a></code>,
except for weakening the restriction to a fixed set of package names so that
any package name other than <code>""</code> is legal. See <a href="INTERN.html">intern</a>. Note that if you
evaluate a call <code>(intern$ x y)</code> for which there is no package with name
<code>y</code> that is known to ACL2, you will get an error.
<p>
<code>(Intern$ x y)</code> expands to:
<pre>
(intern-in-package-of-symbol x (pkg-witness y))
</pre>
See <a href="INTERN-IN-PACKAGE-OF-SYMBOL.html">intern-in-package-of-symbol</a> and see <a href="PKG-WITNESS.html">pkg-witness</a>.
