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