| <p><a name="index-g_t_0040code_007birp_007d-directive-387"></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> |
