Thanks, Hans! This does solve the problem with the list of numbers. And actually if I add a numberstyle field, I can the section heads the way I like. Here is the setup that worked. (I will update Wiki later.) \setupdirections[bidi=global,method=two] \setupalign[r2l] \def\LTR#1{{\lefttoright#1}} \def\leftpersiandecimals#1{\LTR{\persiandecimals{#1}}} \defineconversion[leftpersiandecimals][\leftpersiandecimals] \setuphead[chapter,title,section,subject] [conversion=leftpersiandecimals,numberstyle=\righttoleft] \defineseparatorset[dashsep][-,-,-,-] \setuphead[section][sectionseparatorset=dashsep] On Mon, Apr 11, 2016 at 10:46 AM, Hans Hagen wrote: > On 4/11/2016 4:25 AM, Mohammad Hossein Bateni wrote: > >> Hans & Wolfgang, >> >> Do you have suggestions here?
