Hello, Thanks, but if I omit second argument, no skip is produced (I often to this to have a place for writing number by pen). How to save the skip with \author{Bla-bla}? I'd even rather don't have skip if second argument is provided :) Regards, Vyatcheslav

\define[2]\author{{\itx (#1)}{\hfill\tx bpm=#2\hskip1cm}}

\starttext

\showframe \author{Bla-bla}{foo}

\stoptext

In this context it is also safe to use a fixed space like '\hbox to 1cm{}', but that is cheating. ;)

Best wishes, Peter
