| <p><a name="index-g_t_0040code_007birpc_007d-directive-373"></a>Evaluate a sequence of statements assigning different values to <var>symbol</var>. |
| The sequence of statements starts at the <code>.irpc</code> directive, and is |
| terminated by an <code>.endr</code> directive. For each character in <var>value</var>, |
| <var>symbol</var> is set to the character, 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"> .irpc param,123 |
| 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 the discussion |
| at See <a href="Macro.html#Macro">Macro</a>. |
