So after a few hours of work, we’ve successfully ported the OMicroB Virtual Machine for OCaml to the Numworks calculator 
! See this part of our discussion on GitHub, if anyone is curious.
But we’re far away from being done! Indeed, I want to be able to interpret on the calculator some OCaml line of code / or entire file.
I know it’s probably going to be hard, if not entirely impossible, but hey we’ve at least progressed a bit in this direction! Thanks @borisd again for the suggestion!
@Vertmo is helping me on this issue, thanks to him.
