<p>Every symbol has, as well as its name, the attributes &ldquo;Value&rdquo; and
&ldquo;Type&rdquo;.  Depending on output format, symbols can also have auxiliary
attributes.
</p>
<p>If you use a symbol without defining it, <code>as</code> assumes zero for
all these attributes, and probably won&rsquo;t warn you.  This makes the
symbol an externally defined symbol, which is generally what you
would want.
