|
||
|
|
It is synonymous with ‘<samp><span class="samp">.set</span></samp>’; see <a href="Set.html#Set"><code>.set</code></a>.
|
||
|
|
|
||
|
|
<p>The syntax for <code>equ</code> on the HPPA is
|
||
|
|
‘<samp><var>symbol</var><span class="samp"> .equ </span><var>expression</var></samp>’.
|
||
|
|
|
||
|
|
<p>The syntax for <code>equ</code> on the Z80 is
|
||
|
|
‘<samp><var>symbol</var><span class="samp"> equ </span><var>expression</var></samp>’.
|
||
|
|
On the Z80 it is an eror if <var>symbol</var> is already defined,
|
||
|
|
but the symbol is not protected from later redefinition.
