SBTCVM's CPU makes some progress, as the cpu is now equipped with a whopping 2 stacks.
Along with the cpu, SBTCVM Gen 2-9 is now capable of interactive programs, thanks to a new TTY Input device, that allows for a basic serial text interface.
Aside from the usual assembly enhancements, SSTNPL has gotten its share of changes too:
- you can now create variables based on character code values.
- you can read from the tty input buffer into a variable for easy parsing of keystrokes.
- return is now stackable.
- separate subroutine gotos are required to use return.
- conditional returns are now available.
