<h2>Description</h2>
<p>
These statements are global value <a class="link" href="assign.html" title="="><em class="citetitle">assignments</em></a>, made at the beginning of an orchestra, before any instrument block is defined. Their function is to set certain <a class="link" href="OrchKvar.html#VariableTypes" title="Table 3. Types of Variables"><em class="citetitle">reserved symbol variables</em></a> that are required for performance. Once set, these reserved symbols can be used in expressions anywhere in the orchestra.

<span class="emphasis"><em>nchnls</em></span> = (optional) -- set number of channels of audio output to <span class="emphasis"><em>iarg</em></span>. (1 = mono, 2 = stereo, 4 = quadraphonic.) The default value is 1 (mono).
