<a name="index-current-address"></a>
<a name="index-location-counter"></a>
<p>The special symbol &lsquo;<samp>.</samp>&rsquo; refers to the current address that
<code>as</code> is assembling into.  Thus, the expression &lsquo;<samp>melvin:
.long .</samp>&rsquo; defines <code>melvin</code> to contain its own address.
Assigning a value to <code>.</code> is treated the same as a <code>.org</code>
directive.
Thus, the expression &lsquo;<samp>.=.+4</samp>&rsquo; is the same as saying
&lsquo;<samp>.space 4</samp>&rsquo;.
