When I was a little kid, we had these eight bit home computers. To start anything you needed to type a BASIC command. The machine had a BASIC interpreter in it and came with a BASIC manual. If you had the smallest inclination towards programming, it was shockingly easy to go ahead and hack a program together. And then the BASIC interpreters have disappeared from the machines. The proliferation of GUIs made coding a little bit harder but still you could add something like Delphi to your Windows PC and hack ahead happily.
