  67. <p><var>repeat</var>, <var>size</var> and <var>value</var> are absolute expressions.
  68. This emits <var>repeat</var> copies of <var>size</var> bytes. <var>Repeat</var>
  69. may be zero or more. <var>Size</var> may be zero or more, but if it is
  70. more than 8, then it is deemed to have the value 8, compatible with
  71. other people&rsquo;s assemblers. The contents of each <var>repeat</var> bytes
  72. is taken from an 8-byte number. The highest order 4 bytes are
  73. zero. The lowest order 4 bytes are <var>value</var> rendered in the
  74. byte-order of an integer on the computer <code>as</code> is assembling for.
  75. Each <var>size</var> bytes in a repetition is taken from the lowest order
  76. <var>size</var> bytes of this number. Again, this bizarre behavior is
  77. compatible with other people&rsquo;s assemblers.
  78. </p>
  79. <p><var>size</var> and <var>value</var> are optional.
  80. If the second comma and <var>value</var> are absent, <var>value</var> is
  81. assumed zero. If the first comma and following tokens are absent,
  82. <var>size</var> is assumed to be 1.
