Good evening.
Is there some restriction to Metapost macros when compiled by texexec
--mptex? I'd like to compile a file like this:
% test
input TEX;
beginfig(1)
z1=(0,1cm);
z2=(3cm,1cm);
dotlabel.top(btex $z_1$ etex,z1);
dotlabel.top(btex $z_2$ etex,z2);
draw TEX("$\underbrace{\hbox to
"&decimal(xpart(z2)-xpart(z1))&"pt{\hss}}$") shifted z1;
endfig;
end.
But I've got a following error:
This is MetaPost, Version 0.641 (Web2C 7.3.1)
(TEXuse.mp (/usr/share/texmf/metapost/base/TEX.mp) (mptextmp.mp
>> mptextmp.mp
>> mptextmp.mpx
! Unable to make mpx file.
l.1 btex
$\underbrace{\hbox to 85.03935pt{\hss}}$ etex
Transcript written on TEXuse.log.
error in metapost run : TEXuse.mp:1
What's wrong? How can I improve it?
Many thanks for any hint.
M.K.
P.S. I use TeXExec 3.3 with Metapost Version 0.641 (Web2C 7.3.1) under
Linux (teTeX).

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
