<h2>Description</h2>
<p>
Allows text to be displayed from instruments like sliders etc. (only on Unix and Windows at present)

<div class="refsect1" title="Syntax">
<a id="idp20356576"></a>
<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>flashtxt</strong></span> iwhich, String</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="idp20367184"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>iwhich</em></span> -- the number of the window.
</p>
<p>
<span class="emphasis"><em>String</em></span> -- the string to be displayed.
</p>
</div>
<div class="refsect1" title="Performance">
<a id="idp20368584"></a>
<h2>Performance</h2>
<p>
Note that this opcode is not available on Windows due to the implimentation of pipes on that system
</p>
<p>
A window is created, identified by the iwhich argument, with the text string displayed. If the text is replaced by a number then the window id deleted. Note that the text windows are globally numbered so different instruments can change the text, and the window survives the instance of the instrument.
</p>

<h2>Examples</h2>
