\startsetups header:right

\line{\hfil{\sc a Title}\hfil\hfil\pagenumber\hfil}

\stopsetups

\startsetups header:left

\line{\hfil\pagenumber\hfil\hfil{\sc author}\hfil}

\stopsetups

% Line below the header, you can more solutions in the mail archive

\setupheader[text][after=\hrule]

% header content: alternative a

\setuppagenumbering[location=,alternative=doublesided]
\setupheadertexts[\setups{header:right}][][][\setups{header:left}]

% header content: alternative b

\setuppagenumbering[location=]
\setupheadertexts[\doifoddpageelse{\setups{header:right}} 
{\setups{header:left}}]

\startstandardmakeup[align=middle]

{\definedfont[SansBold sa \magfactor{1}]a Title}

\blank[2cm]

{\definedfont[SansBoldItalic sa \magfactor{1}]a Subtitle}
