Some code that worked ok but hasn't been used for some time, now gives an error: missing $.
It is working fine in ConTeXt, but putting it inside an MPpage goes wrong.
Here a minimal example, the output of the ConTeXt run and the error on the MPpage run.
Has something changed I missed?
Hans van der Meer
The error occurs in this code, my suspect is the cases macro.
\starttext
\startsetups[dif-1]
$\displaystyle
\Delta_{in} = 1000_2 \cases{(A,2)(2,A)&\cr (6,E)(E,6)&\cr}
\buildrel S_1 \over \rightarrow \quad
\Delta_{uit} = 1011_2 \cases{(6,D)(D,6)&\cr (B,0)(0,B)&\cr}
$
\stopsetups
\startMPpage
label("\setup[dif-1]",origin);
\stopMPpage
\stoptext

The ConTeXt run itself is ok, see below

That was a tricky one to nail down ... it related to the fact that have
\{ and \} have a different meaning when we flush metapost text (makes me
wonder if that is still needed)
this helps
