Hi, I hope that this is the right address to post my question. If not I would be glad for a tip. I wanted to do something like this: _______________________ \unprotect %This line uncommented leads to an error \def\tit{Oops!} \def\Teil{\dodoubleempty\doTeil} \def\doTeil[#1][#2]#3{% \def\tit{#1} %... \startchapter[title={\tit},reference={#2}] #3 \stopchapter %... } \protect \starttext \completecontent \doTeil[Hallo][hallo]{Text Text Text Text Text Text Text} \stoptext _______________________ It works if i use #1 direct (like this): \startchapter[title=#1,reference={#2}] But how can I wrap it in the \tit? (wrapping #2 works fine) I wanted to programm \doTeil so, that I can nest it freely (for example with \input) and the table of content uses the hierarchy of the nesting to produce a nice TOC. thanks for help. Sincerely, Harry
