Welcome to the club ;)

You can use \newcounter for such stuff or the context recurse functions
(with \recurselevel).


\starttext

\dostepwiserecurse{1}{9}{1}{% count from 1 to 9, step 1
  \setvalue{PREFIX\recurselevel}{\recurselevel}
}

% or all by hand (not useful for simple loops)
\newcounter\Row % Row=0
\increment\Row % Row+=1
\doloop{%
  \setvariables[PREFIX\Row][foo=foo\Row]
  \increment\Row
  \ifnum\Row>9 \exitloop\fi
}

% reset to one by hand
\newcounter\Row
\increment\Row

\dostepwiserecurse{1}{9}{1}{%
  \getvariable{PREFIX\Row}{foo}=
  \getvalue{PREFIX\recurselevel}\crlf
  \increment\Row
}

\stoptext


You can combine x counters to simulate a x-dimensional array (but you
better wait for lua). Hope that helps.

Greetings, Peter
