Good evening.

i can't see what goes wrong there (this tex in mp stuff is such a mess) from within context the following works ok: \starttext \startMPpage[offset=4cm] z1=(0,1cm); z2=(3cm,1cm); dotlabel.top(btex $z_1$ etex,z1); dotlabel.top(btex $z_2$ etex,z2); draw textext("$\string\underbrace{\hbox to "&decimal(xpart(z2)-xpart(z1))&"pt{\hss}}$") shifted .5[z1,z2]; \stopMPpage \stoptext or: \starttext \let\normalunderbrace\underbrace \unexpanded\def\underbrace{\normalunderbrace} % hm, i need to make these unexpanded \startMPpage[offset=4cm] z1=(0,1cm); z2=(3cm,1cm); dotlabel.top(btex $z_1$ etex,z1); dotlabel.top(btex $z_2$ etex,z2); draw textext("$\underbrace{\hbox to "&decimal(xpart(z2)-xpart(z1))&"pt{\hss}}$") shifted .5[z1,z2]; \stopMPpage \stoptext Hans
