Confusion regarding register use and occupancy calculator

BINGO!

After removing the FILE* and the interaction stuff there are no runtime errors from any kernel!

Thankyou very much Avidday and Tera for all your help. I’ll never forget about that limit now!

:D

Just out of curiosity: Does removing only the FILE pointer make it work already?

And to answer the other question you ask a few times without getting an answer: The occupancy calculator marks in red the parameters that limit occupancy, i.e. where it is worth trying to reduce them.
