<p><a name="index-g_t_0040code_007birpc_007d-directive-388"></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>.
