So far, we have hacked through basic /Free structure and the control statements that can be used to tame it and bend it to our will.

Editor's Note: This article is excerpted from chapter 6 of 21st Century RPG: /Free, ILE, and MVC, by David Shirey.
But what about files? So far, we have not really talked about them. How cruelly unfair, as files are at the heart of everything we do. But that is about to change.
As we shall see, most of the changes are to do with RPG I/O, not the way embedded SQL is used, but we will talk about that briefly also. SQL in full is definitely another topic for another day and has very little to do with /Free per se.
