I guess I didn't make myself clear.
\startMPinitializations
numeric n; n=4cm;
\stopMPinitializations
Now I can use “n” in all MP instances (unless switched off for the
particular instance). I'd like to define some variables only visible
in instance “foo”. Something like
\startMPinitializations [foo]
numeric n; n=4cm;
\stopMPinitializations
I tried
\startMPcode{foo}
numeric n; n=4cm;
\stopMPcode
but this adds some vertical space and doesn't seem to be the right
solution given the face that there are already three other
environments to include MetaPost code. Maybe I'm missing the obvious
here.
