Thanks for the response. I am looking at something like this:

==============
\starttext
\directlua{total = 0}
\title{Homework 1}

Total score: \directlua{tex.print(total);}

Question 1 (3 points)
\directlua{total = total + 3}

Question 2 (4 points)
\directlua{total = total + 4}

Question 3 (5 points)
\directlua{total = total + 5}

\stoptext
==============

I expect the “Total score” to be followed by “12”, but I don't know
how to get that (or whether that is even possible).

Thanks.

Kumar
