<h4 class="subsection">9.54.3 Assembler Directives for the Z8000</h4>

<p><a name="index-Z8000-directives-2539"></a><a name="index-directives_002c-Z8000-2540"></a>The Z8000 port of as includes additional assembler directives,
for compatibility with other Z8000 assemblers.  These do not begin with
&lsquo;<samp><span class="samp">.</span></samp>&rsquo; (unlike the ordinary as directives).

     
<a name="index-segm-2541"></a>
<dl><dt><code>segm</code><dd><a name="index-g_t_002ez8001-2542"></a><dt><code>.z8001</code><dd>Generate code for the segmented Z8001.

     <p><a name="index-unsegm-2543"></a><br><dt><code>unsegm</code><dd><a name="index-g_t_002ez8002-2544"></a><dt><code>.z8002</code><dd>Generate code for the unsegmented Z8002.

     <p><a name="index-name-2545"></a><br><dt><code>name</code><dd>Synonym for <code>.file</code>

     <p><a name="index-global-2546"></a><br><dt><code>global</code><dd>Synonym for <code>.global</code>

     <p><a name="index-wval-2547"></a><br><dt><code>wval</code><dd>Synonym for <code>.word</code>

     <p><a name="index-lval-2548"></a><br><dt><code>lval</code><dd>Synonym for <code>.long</code>

     <p><a name="index-bval-2549"></a><br><dt><code>bval</code><dd>Synonym for <code>.byte</code>

     <p><a name="index-sval-2550"></a><br><dt><code>sval</code><dd>Assemble a string.  <code>sval</code> expects one string literal, delimited by
single quotes.  It assembles each byte of the string into consecutive
addresses.  You can use the escape sequence &lsquo;<samp><span class="samp">%</span><var>xx</var></samp>&rsquo; (where
<var>xx</var> represents a two-digit hexadecimal number) to represent the
character whose <span class="sc">ascii</span> value is <var>xx</var>.  Use this feature to
describe single quote and other characters that may not appear in string
literals as themselves.  For example, the C statement &lsquo;<samp><span class="samp">char&nbsp;*a&nbsp;=&nbsp;"he&nbsp;said&nbsp;\"it's&nbsp;50%&nbsp;off\"";</span></samp>&rsquo;<!-- /@w --> is represented in Z8000 assembly language
(shown with the assembler output in hex at the left) as

     <pre class="smallexample">          68652073    sval    'he said %22it%27s 50%25 off%22%00'
          61696420
          22697427
          73203530
          25206F66
          662200
</pre>
     <p><a name="index-rsect-2551"></a><br><dt><code>rsect</code><dd>synonym for <code>.section</code>

     <p><a name="index-block-2552"></a><br><dt><code>block</code><dd>synonym for <code>.space</code>

     <p><a name="index-even-2553"></a><br><dt><code>even</code><dd>special case of <code>.align</code>; aligns output to even byte boundary.
