<h4 class="subsection">9.56.2 Syntax</h4>
<p>The assembler syntax closely follows the &rsquo;Z80 family CPU User Manual&rsquo; by
Zilog.
In expressions a single &lsquo;<samp>=</samp>&rsquo; may be used as &ldquo;is equal to&rdquo;
comparison operator.
</p>
<p>Suffices can be used to indicate the radix of integer constants;
&lsquo;<samp>H</samp>&rsquo; or &lsquo;<samp>h</samp>&rsquo; for hexadecimal, &lsquo;<samp>D</samp>&rsquo; or &lsquo;<samp>d</samp>&rsquo; for decimal,
&lsquo;<samp>Q</samp>&rsquo;, &lsquo;<samp>O</samp>&rsquo;, &lsquo;<samp>q</samp>&rsquo; or &lsquo;<samp>o</samp>&rsquo; for octal, and &lsquo;<samp>B</samp>&rsquo; for
binary.
</p>
<p>The suffix &lsquo;<samp>b</samp>&rsquo; denotes a backreference to local label.
