Dear all,
I should prepare a form with a table. The table rows should be numbered.
How can I get get this done by using \recurselevel.
In the attached minimal example all rows are numbered with 0.
\starttext
\subject{bTABLE--eTABLE: recurse creates rows}
\bTABLE
  \dorecurse{3}
      {\bTR
      	\bTD \recurselevel \eTD
      \eTR}
\eTABLE
What do i do wrongly here?
You’re doing nothing wrong but you have to expand the value of the counter.
One feature of natural tables is the calculated width of the cells, to do this context stores
the content of all cells in a token register, i.e. context stores \recurselevel as content
of the cell and not the value of the iteration. This content is processed after all cells
have been stored and the \recurselevel macro uses at this moment its default value 0.
To expand the value of the counter use \expanded{…} to force a expansion.
\bTABLE
 \dorecurse{3}{\bTR\bTD\recurselevel\eTD\eTR}
\eTABLE
Needs \expanded:

\bTABLE
  \dorecurse{3}{\bTR\expanded{\bTD\recurselevel\eTD}\eTR}
\eTABLE
