Unless I'm doing something very silly, the following should and I am
almost certain did work, but it fails with the 2006.09.28 beta:
================ btex.tex ===================
\starttext
\startreusableMPgraphic{fig}
label(btex in b/e tex etex, origin);
\stopreusableMPgraphic
outside btex..etex\quad
\reuseMPgraphic{fig}
\stoptext
============================================
The output says
systems : begin file btex-mpgraph-temp at line 42
! Missing $ inserted.
<inserted text>
$
<to be read again>
_
l.48 _
special_div_ := 10000;
?
Here's a snippet from btex-mpgraph-temp.tex:
\starttext
\startMPXpage
"
mpgraph:=1;
randomseed:=33;
_special_div_ := 10000;
The underscores in the variable name are upsetting to tex. I haven't
tracked down the chain of influence that put them there.
Meanwhile the same btex..etex test on a static MP figure works fine:
==================== btex-static.tex ================
\starttext
\startstaticMPfigure{fig}
label(btex in b/e tex etex, origin);
\stopstaticMPfigure
outside btex..etex\quad
\usestaticMPfigure[fig]
\stoptext
====================================================
