<h1>Labels</h1>
<p>One of the assembler’s main tasks is to keep track of addresses for you so you dor’t have to remember obscure numbers but can make do with a meaningful name, a label.</p>
<p>This can be done in a number of ways:</p>
<pre>GlobalLabel
AnotherGlobal:
.locallabel
.yet_a_local:
ThisWillBeExported:: ;note the two colons</PRE>
</FONT></TD>
</TR>
</TABLE>
<P>This is very similar to other assemblers. Local labels are only accessible within the scope they are defined. A scope starts after a global label and ends at the next global label. You may or may not have seen the <B>::</B> feature before. It declares a normal global label but does an <A HREF="export.htm">EXPORT</A> at the same time.<BR>
<P>Labels will normally change their value during the <A HREF="../link.htm">link process</A> and are thus <B>not</B> constant.<BR>
