<h2>Initialization</h2>
<p>
<span class="emphasis"><em>size</em></span> -- number of points in the table. Must be a power-of-2 plus 1 (see <a class="link" href="f.html" title="f Statement (or Function Table Statement)">f</a> statement).
</p>
<p>
<span class="emphasis"><em>fna, fnb, etc.</em></span> -- pre-existing table number to be written into the table.
</p>
<p>
<span class="emphasis"><em>ampa, ampb, etc.</em></span> -- strength of wavefoms. These are relative strengths, since the composite waveform may be rescaled later. Negative values are permitted and imply a 180 degree phase shift.
</p>
<p>
<span class="emphasis"><em>starta, startb, etc.</em></span> -- where to start writing the fn into the table.
