List Operators (Rightward)</h2><p><a name="INDEX-1016"></a>The right side of a list operator governs all the list operator'sarguments, which are comma separated, so the precedence of a listoperator is lower than a comma if you're looking to the right. Once alist operator starts chewing up comma-separated arguments, the onlythings that will stop it are tokens that stop the entire expression(like semicolons or statement modifiers), or tokens that stopthe current subexpression (like right parentheses or brackets), orthe low precedence logical operators we'll talk about next.</p><!-- BOTTOM NAV BAR --><hr width="515" align="left"><div class="navbar"><table width="515" border="0"><tr><td align="left" valign="top" width="172"><a href="ch03_18.htm"><img src="../gifs/txtpreva.gif" alt="Previous" border="0"></a></td><td align="center" valign="top" width="171"><a href="index.htm"><img src="../gifs/txthome.gif" alt="Home" border="0"></a></td><td align="right" valign="top" width="172"><a href="ch03_20.htm"><img src="../gifs/txtnexta.gif" alt="Next" border="0"></a></td></tr><tr><td align="left" valign="top" width="172">3.18.
