Yes, thank you. I tried "context()" several times, but without success.
Could be, that I have a false meaning how to use it: If I transfer data
from context to lua and vice versa then in my imagination there must be 
variables in both languages  where the sent data is to be found.

With the use of "\immediate\write" and "\read" in context and the read and write
functions in lua I know exactly from where to where the data goes. How to do 
the same with "context()"?
