This is a disclaimer to my former message about this subject. I continued considering the solution to the problem of using *fleurons* in a document via the suggested *\leaders* command and it turned out to be a dead end for the following reasons: 1) it acts wrongly if the page in which the *fleuron* is to appear has a lot of blank space availabe, as the following test code demonstrates: \setuplayout[lines=30] \def\Fleuron {\par \leaders\vbox to \lineheight{\midaligned{Finis\\coronat\\opus}}\vfil} \starttext \dorecurse{32}{Line \recurselevel\par} \Fleuron \stoptext where the intended *fleuron* appears superposed several times instead of the only one desired; 2) the use of such an instruction is touchy and not dependable. As I have experienced, things work satisfactorily or not according to the degree of nesting of the command *\fleuron* in the whole launching command and possibly according to many other unnoticed factors; 3) the suggested formulation does not allow enough control for the placement of the *fleuron* in the final document. In the end all this seems reasonable: the straigth use of the *\leaders* command is almost the contrary of the one demanded for the present functionality. The effect of the (obscure in more than one sense) *Tex* command *\leaders* is to fill a (rather implicitly defined) surface with repeated copies of a certain motive. The visibility or not of the result according to the surrounding text or space in the page has to be considered therefore as a purely accidental (and noxious) side effect. The content typesett via *\leaders* is not supposed in any way to disappear when following lines are added. I conclude that the only lawful use of *\leaders* in the true context of *fleurons* would be for the generation of certain repetitive motives (for instance a kind of small checkered board), but this is only a hint; I have not explored this possibility. Fortunately I have been able to advance in another direction and to get what seems to me a consistent solution to the original problem. I open the new thread *Using *fleurons** for explaining it more fully. Regards Francisco

\dorecurse{32}{Line \recurselevel\par}
\Fleuron
\stoptext
where the intended *fleuron* appears superposed several times instead of the only one desired; You can avoid this when you limit the space for the leaders command.
