It assembles each byte of the string into consecutive addresses. You can use the escape sequence ‘<samp><span class="samp">%</span><var>xx</var></samp>’ (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 ‘<samp><span class="samp">char *a = "he said \"it's 50% off\"";</span></samp>’<!-- /@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. </dl> </body></html>
