\starttext
\define\question{44}
\startluacode
-- see "ConTeXt Lua Documents" manual, ยง7.4 Looking inside
local question = tokens.getters.macro("question")
-- it's up to you to verify that \question contains a number
-- better using the userdata table for your data
userdata.points = tonumber( question ) * 92
-- do some calculations with points and return to to context
userdata.answer=42
\stopluacode
% lots of Text in between
The answer is \ctxlua{ context(userdata.answer) }. Points are \ctxlua{
context(userdata.points) }.
\stoptext
Best wishes,

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
