The number of elements of each vector (length of the vector) is determined by the number of optional arguments on the right (<span class="emphasis"><em>inarg1</em></span>, <span class="emphasis"><em>inarg2</em></span>, <span class="emphasis"><em>inarg3</em></span>, .... <span class="emphasis"><em>inargN</em></span>). </p> <p> Notice that no wrap nor limit mode is implemented. So, if an index attempt to access to a zone not allocated by the table, Csound will probably crash. However this drawback can be easily avoided by using wrap or limit opcodes applied to indexes before using <span class="emphasis"><em>vtabwi</em></span>, in order to correct eventual out-of-range values. </p> </div> <div class="refsect1"> <a id="idm281472869543608"></a> <h2>Credits</h2> <p>Written by Gabriel Maldonado.</p> <p>New in Csound 5 (Previously available only on CsoundAV)</p> </div> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="vtaba.html">Prev</a> </td> <td width="20%" align="center"> <a accesskey="u" href="OpcodesTop.html">Up</a> </td> <td width="40%" align="right"> <a accesskey="n" href="vtabwk.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">vtaba </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> vtabwk</td> </tr> </table> </div> </body> </html>
