An interesting default for recurselevel in xetex
Hi, Guess what happens when you run this with xetex \starttext\recurselevel\stoptext This is a side effect of the definition of \dofastrecurse. After using \dofastrecurse, the default value of recurselevel is \number\fastrecursecounter rather than 0. I don't think that this will have any side effects. Aditya

no, it's just the last value; of course i can set it to zero recurselevel is also known inside \doloop so there it makes sense to have it afterrwards (or when using \exitloop in any case) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Both \dorecurse and \doloop leave the value of \recurselevel to its previous value. \dofastrecurse does not and sets it to the last value. \starttext \recurselevel \dorecurse{6}{Hello } \recurselevel \doloop{\ifnum\recurselevel>6\relax \exitloop\else again \fi} \recurselevel \dofastrecurse{1}{6}{1}{and again} \recurselevel \stoptext I do not think that any change is needed (One shouldn't use \recurselevel outside a recursion macro anyways). I was just surprised to find that recurselevel was defaulting to such a weird value in xetex. Aditya

also in luatex but that will probably change once we have more direct access at the lua end anyhow, here's teh way out \def\dodofastrecurse {\ifnum\fastrecursecounter>\lastrecursecounter \let\recurselevel\!!zerocount \else \fastrecursebody \advance\fastrecursecounter\steprecursecounter \expandafter\dodofastrecurse \fi} Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
