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? knd regards Willi

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 Wolfgang

Thank you again! Sorry for misspelling your name Aditya! I was surprised, that the solution of Wolfgang does not work, with \expanded{\recurselevel}, though it sounds reasonable. Still all rows are marked 0. Alan's suggestion gives me the desired result. Hm, I was not yet thinking about using cld... Thank you Hans! Willi On Mar 17, 2013, at 10:52 PM, Hans Hagen wrote:

See my change, you have to put \expanded before \bTD because when you write \bTD \expanded{\recurselevel} \eTD context will store “\expanded{\recurselevel}” which is expanded after all cells are created and \recurselevel has its default value. Wolfgang
