Many thanks for your response, but unfortunately it does not solve my
problem. In your solution, var in TestVarB is the identifier of the
reference, which is "1", but I need the value of the reference, that is,
the number of the line where the \someline command is being called,
which is "31" or so. I want to access the value in Lua to do some
calculations on it before returning the result to TeX.
Best regards,
Oliver
