Just for fun I signed up for free IBM mainframe linux access to see whether SmallBASIC could compile and run.
https://developer.ibm.com/linuxone/It turned out to be a useful exercise because it led to a bug discovery and an idea for minor code optimization.
So now you can run the command line version of SmallBASIC on a mainframe, I'm not sure how useful this would be to anyone but its still kind of cool.
