<a name="index-location-counter"></a>
|
|
<p>The special symbol ‘<samp>.</samp>’ refers to the current address that
|
|
<code>as</code> is assembling into. Thus, the expression ‘<samp>melvin:
|
|
.long .</samp>’ 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 ‘<samp>.=.+4</samp>’ is the same as saying
|
|
‘<samp>.space 4</samp>’.
