it depends on what you want to calculate
\startMPcalculation
path p, q;
h := PaperHeight;
w := PaperWidth;
p = (0, 0) -- (w, .5h);
q = (0, h) -- (w, 0);
z0 = p intersectionpoint q;
passvariable("z",ypart z0) ;
\stopMPcalculation
\setuplayout
[topspace=0pt,
header=0pt,
height=\MPrunvar{z}bp]
\showgrid
\starttext
xyz:\MPrunvar{z}
\stoptext
