								<p><a name="index-_0040code_007birp_007d-directive-370"></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@-
