There’s no direct way -round this: how would you express a 10th argument? — and ensure that -the syntax didn’t gobble some other valid usage? -<p/>If you really must have more than 9 arguments, the way to go is: -<blockquote> -<pre> -\def\blah#1#2 ... #9{% - \def\ArgI{{#1}}% - \def\ArgII{{#2}}% - ... - \def\ArgIX{{#9}}% - \BlahRelay -} -\def\BlahRelay#1#2#3{% - % arguments 1-9 are now in - % \ArgI-\ArgIX - % arguments 10-12 are in - % #1-#3 - <macro body>% -} -</pre> -</blockquote><p> -This technique is easily extendible by concert pianists of the TeX -keyboard, but is really hard to recommend. -<p/>LaTeX users have the small convenience of merely giving a number of -arguments in the <code>\</code><code>newcommand</code> that defines each part of the -relaying mechanism: Knuth’s restriction applies to <code>\</code><code>newcommand</code> -just as it does to <code>\</code><code>def</code>. However, LaTeX users also have the -way out of such barbarous command syntax: the <i>keyval</i> -package.
