Hello, What \stelinterliniein means in the following (taken from Skdk style). \def\StartTitlePage% {\startstandardmakeup[doublesided=no] \setupbackgrounds[header][text][background=] \switchtobodyfont[ss,18pt] \setupalign[right] \setupindenting[0pt] \stelinterliniein \vfil \let\\=\blank} I suppose that it is \setupinterlinespace, but it does not work without arguments, as seen in my minimal example: --------------- \setuphead [Part] [number=no, style={\ss\bfd}, page=right] \def\StartTitlePage% {\startstandardmakeup[doublesided=no] \setupbackgrounds[header][text][background=] \switchtobodyfont[ss,18pt] \setupalign[right] \setupindenting[0pt] \setupinterlinespace \vfil \let\\=\blank} \def\StopTitlePage% {\vfill {\tfx Version \currentdate[year,-,mm,-,dd] } \stopstandardmakeup } \def\TitlePage#1{\StartTitlePage\Part{#1}\StopTitlePage} \starttext \TitlePage{Hello} \stoptext ------------------------ Regards, Vyatcheslav
