When I create animations using MetaPost, I typically do something like
for n=1 upto N:
beginfig(n);
<some code>
endfig;
endfor;
and a sequence of figures are created. How can I do this in ConTeXt using
\startMPpage ... \stopMPpage?

(untested)
\dorecurse{10}
{\startMPpage
label(btex On step \recurselevel etex, origin);
\stopMPpage}
(There is also \dostepwiserecurse if you need more control).

That works great. Now I have defined a global numeric
N:=8;
in \startMPinclusions ... \stopMPinclusions at the be beginning of my
document. All of my \startMPpage ... \stopMPpage environments understand
this N, but how do I reference this value as the start value for
\dostepwiserecurse? That is, I would like to do something like
\dostepwiserecurse{N}{0}{-1}{ ... <some code> ... }

For that, you'll need to work on the TeX end.
\edef\STEPS{8}
\dorecurse\STEPS{....}
You can either use \STEPS instead of N everywhere in your code (and be
careful on how TeX code is parsed, i.e., `a := \STEPS 0` will evaluate to
`a := 80`), or use `N := \STEPS;` somewhere in the beginning of each
`\MPpage` (the `N :\ \STEPS` can be hidden behind a macro like
`\initializeAnimation`).

That works great too. One more question now. I would like a particular
MetaPost label to contain the value of a variable, say n. I don't want to
use
label(decimal(n),origin);
because I want the label to be a TeX picture instead of a string. That is,
I would like to have
label(btex n etex,origin);
where n is the VALUE of n and not the letter n.
Thanks,
Troy
