Hi, I am trying to pass variables/data between context and lua. Lua would be 
used for
calculations on data coming from context.

Unfortunately I can't figure out what to do. The code below doesn't work, but 
is there to
illustrate my idea. 

Any help would be much appreciated. Thanks, Martin 


\define\question{44}

\starttext

\startluacode
local points = \question * 92
-- do some calculations with points and return to to context
answer=42
\stopluacode

% lots of Text in between 
The answer is \answer

\stoptext
