[NTG-context] \define with more than 9 parameters??

6 Jun 2013

      Hello ConTeXist.
Is there in ConTeXt any dirty trick, which can put more than 9 
parameters into macro?

I mean for example \define[25]\macrowithtwentyfiveparams{ .... }

I use rarely any trick from Peter Olsak (see below) and I'd like 
something like that used in ConTeXt.

Thanx

Here is minimal example of trick of Petr Olsak:

\newcount\tempnum
\def\terminator{*}
\newcount\tempnum
\def\readparameters{\tempnum=0\let\next=\readone \next}
\def\readone #1,{\advance\tempnum by 1 \def\param{#1}%
         %\the\tempnum - \param\par%
     \ifx\param\terminator \let\next=\relax
     \else\expandafter\gdef\csname param\the\tempnum\endcsname{#1}%
     \fi\next}

\def\moreparameters#1{%
  \readparameters #1 %
  \csname param1\endcsname, % write first parameter
  \csname param3\endcsname, % write third parameter
  \csname param5\endcsname, % write fifth parameter
}

%\readparameters a,b,c,d,e,f,g,h,i,j,k,m,n,o,*, %
%\def\parameters{aaa,bbbb,cccc,dddd,eeeee,fffff,ggggg,*,}
%\expandafter\readparameters\parameters

\moreparameters{a,b,c,d,e,f,g,h,i,j,k,m,n,o,*,}
