Operations which produce a result formally run at the rate of that result (that is, at init time for i-rate results; at performance time for k- and a-rate results), with the sole exception of the <span class="emphasis"><em>init</em></span> opcode. Most generators and modifiers, however, produce signals that depend not only on the instantaneous value of their arguments but also on some preserved internal state. These performance-time units therefore have an implicit init-time component to set up that state. The run time of an operation which produces no result is apparent in the opcode. </p> <p> Arguments are values that are sent to an operation. Most arguments will accept arithmetic expressions composed of constants, variables, reserved symbols, value converters, arithmetic operations, and conditional values. </p> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="OrchIblock.html">Prev</a> </td> <td width="20%" align="center"> <a accesskey="u" href="OrchTop.html">Up</a> </td> <td width="40%" align="right"> <a accesskey="n" href="OrchKvar.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">Instrument and Opcode Block Statements </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> Types, Constants and Variables</td> </tr> </table> </div> </body> </html>
