Hi,
I am using ConTeXt ver: 2008.09.10 14:01 MKIV fmt: 2008.9.11 and the
following file
\starttext
\startMPcode
label.bot(\sometxt{$\mathop{}$}, origin) ;
\stopMPcode
\stoptext
gives
! Missing number, treated as zero.

##
\purenumber ...firstofoneargument \@EA {\number #1
}
\PDFobjref #1->\purenumber {#1}
0 R
l.46 \def\PDFobjref#
1{\purenumber{#1} 0 R}
?
! Missing number, treated as zero.

It runs correctly with MKII. Any ideas?
Aditya

The problem is that everything within \startMPcode ... \stopMPcode
is expanded, but \mathop's (re)definition has \let commands in it.
This works as a workaround:
\startMPcode
label.bot(\sometxt{$\noexpand\mathop{}$}, origin) ;
\stopMPcode
But actually the definition of \mathop in font-ini.tex needs to be
changed so that it won't be expandable any more. The current definition
would give problems in the support files (tuo,tuc) as well.
Best wishes,
Taco

indeed; i already did that, but more math commands might need that treatment
