To print things for the user to see, we use Display. If we want to print and then move to a new line, we use Displaynl.
Display("Hello, ").Displaynl("my friend.").
Sometimes you want the user to type something. You can use Input to capture what they type and keep it in a variable box.
Sentence userName.Display("What is your name: ").Input(userName).Displaynl("Nice to meet you, " + userName).
