The following code produces the letter "J" on the first page, but does not
draw that same picture on the second page. I would appreciate some advice
on how to save and redraw this label in subsequence figures.
Thanks,
Troy Henderson
\starttext
\startMPinclusions[+]
picture J;
\stopMPinclusions
\startMPpage
J:=thelabel(btex J etex scaled 2,origin);
draw J;
\stopMPpage
\startMPpage
draw J;
\stopMPpage
\stoptext

Hans has be playing with MetaPost instances which got broken.
\startMPpage\stopMPpage got the wrong instance
whereas \startTEXpage\startMPcode\stopMPcode\stopMPpage correctly got
the default instance.
Normally, this was fixed, but your minimal example still does not
work for me either. Something else is at cause...
The reasons Hans has modified MP instances are:
1. we wanted to isolate the chemistry drawing macros from other MP use,
but not from the user, and
2. we uncovered an error with mlib when using a very great number of
MP pictures.

vardef J = thelabel(textext("J") scaled 2,origin) enddef ;
\stopMPinclusions
\startMPpage
draw J;
\stopMPpage
\startMPpage
draw J;
\stopMPpage
\stoptext
as text in handled at the tex end it is lost after graphic is done;
imlemeno it ting selective persistence is possible but messy; maybe some
day i'll do it
