Hello,

Thank you all very much. I'm pleased with number and quality of solutions to my problem. Did you look in supp-box at centerbox definition ? it' something like \vbox to \adimension{\vfill ....\vfill} (well, not \vfill, but \vss)

You approach was not so distant to solutions , you only forget that \vfill need a bit of attention. (hey even today sometimes i'm lost with \def and \edef...)

Compare \starttext \vfill a \vfill \stoptext

with \starttext \hskip1sp \vfill a \vfill \stoptext

Given that 1sp is invisible to human eye , one can appreciate here a "butterfly effect" :))

Hi Luigi, you can use \dontleavehmode in this case. \starttext \dontleavehmode\vfill a \vfill \stoptext Wolfgang
