I wrote HaiBas, a BASIC interpreter, in 1975/76 for a software company in The Netherlands. The company and independent developers sold their packages, "apps" in modern parlance, and brought in eventually several thousand end users. It never progressed to a graphical world but there are still enthusiastic developers and end users. I bought the software rights about 10 years ago and have maintained the interpreter and associated tools (now in C++) for nearly 50 years. Significant? Certainly on a personal level!
