<p><a name="index-g_t_0040code_007bstruct_007d-directive-492"></a>Switch to the absolute section, and set the section offset to <var>expression</var>,
|
|
which must be an absolute expression. You might use this as follows:
|
|
<pre class="smallexample"> .struct 0
|
|
field1:
|
|
.struct field1 + 4
|
|
field2:
|
|
.struct field2 + 4
|
|
field3:
|
|
</pre>
|
|
<p>This would define the symbol <code>field1</code> to have the value 0, the symbol
|
|
<code>field2</code> to have the value 4, and the symbol <code>field3</code> to have the
|
|
value 8. Assembly would be left in the absolute section, and you would need to
|
|
use a <code>.section</code> directive of some sort to change to some other section
|
|
before further assembly.
