Playing around with trying to write a repl in BASIC and I ran into the wall of not knowing enough. I'll need to get better at thinking about parsers and language before I take another stab at it. Writing the editor and shell was a good first step but it seems writing an interpreter is different.
Crafting interpreters is really good so I think I'll take a stab at following it again and see if I can figure out how to implement it in BASIC. I remember doing it and being amazed by it. I actually used it to implement a small language for work in javascript which was fun.
Stuff to learn and work to do :)
