This is where all the pieces finally come together on screen. After exploring the DDS, COPYBOOKs, and RPGLE logic, this lesson walks you through running the program and watching the subfile behave in real time. You’ll see how records load, how user actions trigger program responses, and how the display file and RPG logic interact under the hood.
This is your chance to connect theory with practice observing the program’s flow, spotting quirks, and gaining the confidence that comes from seeing your code actually *do* something on the IBM i.
Compile this RPGLE program and see what it does.
In order to Test the RPG program we will have to add a line of code to actually populate the data from the physical file into the screen subfile.
