This is fantastic. I learned to program back in the 90s using QBasic. It came with DOS and along with it a book very much like this PDF. I read through the whole book, entering every line of code in the examples, changing little pieces of it until I understood how it worked. Such good memories. I'll enjoy reading this. Thank you.
