in thread Learning Programming, desperately need to know what information is contained in scalar variables
... the book doesn't want to show you what undef is... Actually it does. And probably choroba meant something different and I quoted him wrong. But I’m pretty sure that he doesn’t worry 🤪😎 Hint: Don’t just copy examples from this splendid book. Invent your own. Play and have fun. Good «trivial examples» are pure fun and hard to figure out... Best regards, Karl
