  77. <p>Copy the characters in <var>str</var> to the object file. You may specify more than
  78. one string to copy, separated by commas. Unless otherwise specified for a
  79. particular machine, the assembler marks the end of each string with a 0 byte.
  80. You can use any of the escape sequences described in <a href="Strings.html#Strings">Strings</a>.
  81. </p>
  82. <p>The variants <code>string16</code>, <code>string32</code> and <code>string64</code> differ from
  83. the <code>string</code> pseudo opcode in that each 8-bit character from <var>str</var> is
  84. copied and expanded to 16, 32 or 64 bits respectively. The expanded characters
  85. are stored in target endianness byte order.

  87. <p>Example:
  88. </p><div class="smallexample">
  89. <pre class="smallexample"> .string32 &quot;BYE&quot;
  90. expands to:
  91. .string &quot;B\0\0\0Y\0\0\0E\0\0\0&quot; /* On little endian targets. */
  92. .string &quot;\0\0\0B\0\0\0Y\0\0\0E&quot; /* On big endian targets. */
