<h3 class="section">7.52 <code>.fill </code><var>repeat</var><code> , </code><var>size</var><code> , </code><var>value</var></h3>

<p><a name="index-g_t_0040code_007bfill_007d-directive-331"></a><a name="index-writing-patterns-in-memory-332"></a><a name="index-patterns_002c-writing-in-memory-333"></a><var>repeat</var>, <var>size</var> and <var>value</var> are absolute expressions. 
This emits <var>repeat</var> copies of <var>size</var> bytes.  <var>Repeat</var>
may be zero or more.  <var>Size</var> may be zero or more, but if it is
more than 8, then it is deemed to have the value 8, compatible with
other people's assemblers.  The contents of each <var>repeat</var> bytes
is taken from an 8-byte number.  The highest order 4 bytes are
zero.  The lowest order 4 bytes are <var>value</var> rendered in the
byte-order of an integer on the computer <samp><span class="command">as</span></samp> is assembling for. 
Each <var>size</var> bytes in a repetition is taken from the lowest order
<var>size</var> bytes of this number.  Again, this bizarre behavior is
compatible with other people's assemblers.

   <p><var>size</var> and <var>value</var> are optional. 
If the second comma and <var>value</var> are absent, <var>value</var> is
assumed zero.  If the first comma and following tokens are absent,
<var>size</var> is assumed to be 1.
