Looking at some threads on Hacker News, there was thread about modern port of Turbo Vision (for those who remember Turbo/Borland Pascal and C). And checking the readme, it was mentioned that this modern version of the library is used by TMBASIC.

For those interested in Turbo Vision port, this is the link on GitHub: https://github.com/magiblot/tvision

Now more for TMBASIC: It is BASIC language for writing non-graphical programs - text user interface only. More interesting is that it runs on multiple OSes - Windows, Linux, MacOS, iOS and Android.
