<p><a name="index-g_t_0040code_007birp_007d-directive-382"></a>Evaluate a sequence of statements assigning different values to <var>symbol</var>.
The sequence of statements starts at the <code>.irp</code> directive, and is
terminated by an <code>.endr</code> directive. For each <var>value</var>, <var>symbol</var> is
set to <var>value</var>, and the sequence of statements is assembled. If no
<var>value</var> is listed, the sequence of statements is assembled once, with
<var>symbol</var> set to the null string. To refer to <var>symbol</var> within the
sequence of statements, use <var>\symbol</var>.
<p>For example, assembling
<pre class="example"> .irp param,1,2,3
move d\param,sp@-
.endr
</pre>
<p>is equivalent to assembling
<pre class="example"> move d1,sp@-
move d2,sp@-
move d3,sp@-
</pre>
<p>For some caveats with the spelling of <var>symbol</var>, see also <a href="Macro.html#Macro">Macro</a>.
