V následujícím kódu je JV adresa v zero page. Na ní je uložen kód instrukce JMP (addr) který je zde uložen v rámci inicializace. Za ní na adresách JV+1 a JV+2, které slouží jako 16-bitový registr, je je uložana adresa následující instrukce.

On the other end of the spectrum, if you want multiple stacks for multiple threads, you can provide 32 deep data stacks and 16 deep return stacks with separate high byte and low byte stacks, giving 8 independent threads with three dedicated pages of RAM:

DL -- low data stack byte, aligned on a page boundary
DH = DL+256
RL = RH+256
RH = RL+128

If you have 8K RAM, with the zero page and hardware stack, this is 1 1/4K, add a page per thread for user variables, PAD, and Pictured numeric input, and you have allocated 5 1/4K, leaving 2 3/4K for I/O and other uses (block buffers, input buffer, serial port buffer)
