(Linux?) https://github.com/M2IHP13-admin/JonesForth-arm Not sure if it’s an APCS-32 EABI though… Anyone want to check it for 32bit and port it over to RISC OS? (And assuming there aren’t to many differences it should be possible to use the BB4WFORTH sources in (FORTH) directly with some tweaking for the platform specfic items.)
