\doifelsemarking
or
\doifelsetext
Thanks, that worked. My final solution (just for the archive, it seems to be more suitable than the solution in the wiki): \define\CustomHeader{% \cap{ \doifelsetext{\getmarking[chapter]}% {Kapitel \getmarking[chapternumber]: \getmarking[chapter]}% {\doifelsetext{\getmarking[section]} {\getmarking[section]} {} }% } } \setupheadertexts[][\CustomHeader{}{~\|~}\pagenumber][\pagenumber][] Huseyin Özoguz E-Mail: h.oezoguz@mmnetz.de Am 10.04.2019 um 13:26 schrieb Hans Hagen:
