<p>printf —
printf-style formatted output

<a id="id3114645"></a>
<h2>Description</h2>
<p>
<span class="command"><strong>printf</strong></span> and <span class="command"><strong>printf_i</strong></span> write
formatted output, similarly to the C function
printf(). <span class="command"><strong>printf_i</strong></span> runs at i-time only, while
<span class="command"><strong>printf</strong></span> runs both at initialization and
performance time.

<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>printf_i</strong></span> Sfmt, itrig, [iarg1[, iarg2[, ... ]]]</pre>
<pre class="synopsis"><span class="command"><strong>printf</strong></span> Sfmt, ktrig, [xarg1[, xarg2[, ... ]]]</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="id3114905"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>Sfmt</em></span> -- format string, has the same format
as in printf() and other similar C functions, except length
modifiers (l, ll, h, etc.) are not supported. The following
conversion specifiers are allowed:

</li>
</ul>
</div>
<p>
</p>
<p>
<span class="emphasis"><em>iarg1, iarg2, ...</em></span> -- input arguments
(max. 30) for format. Integer formats like %d round the input
values to the nearest integer.
</p>
<p>
<span class="emphasis"><em>itrig</em></span> -- if greater than zero the opcode
performs the printing; otherwise it is an null operation.
</p>
</div>
<div class="refsect1" title="Performance">
<a id="id3115588"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>ktrig</em></span> -- if greater than zero and different
from the value on the previous control cycle the opcode
performs the requested printing. Initially this previous value is
taken as zero.
</p>
<p>
<span class="emphasis"><em>xarg1, xarg2, ...</em></span> -- input arguments
(max. 30) for format. Integer formats like %d round the input
values to the nearest integer. Note that only k-rate and i-rate arguments are valid (no a-rate printing)
