Hi Pauli!

Sorry for not beeing fast enough for you. I am highly interested in your hints and private lessons but right now short with time.

But I have tried your push_stack() quick check to "globalize" the local stack and reduced the code from 8118 bytes to 7666 bytes - 452 bytes reduced - that is amazing!!!

Maybe doing this with pull() saves me several bytes too. Fantastic.

I think version 2 of ScArY seems to be close. :-)
