Practical RPG: Processing Stream Files, Part 1

We've all had to process a folder full of files from a PC or a UNIX machine; today we learn how to do it programmatically.

Written by Joe Pluta

If you're like me, you strongly believe that the IBM i is the best choice as your business integration hub. It talks just about any language, can handle any kind of data, and has unparalleled reliability. In fact, it's a prefect interpreter between other systems in your infrastructure. One of the things that IBM has focused on over the years is a fantastic capability to support stream files. Whether it's the UNIX-like capabilities of QShell, the stream file capabilities of commands like CPYFRMIMPF, or the ability to write C programs to directly access the files, there isn't a stream file requirement that can't be met by the IBM i.

RPG Academy: Write Better Code - More Tips for Organizing Your Modules and Service Programs

The previous article of the series discussed module and service program organization. It’s now time to do the same for binding directories.

Written by Rafael Victória-Pereira

Let’s start with a quick recap of binding directories. Your modules will be composed of procedures. Some of these procedures are going to be available to the outside world; these are the module’s exports. The module’s procedures might call procedures from other service programs; these are the module’s imports. The problem is that the compiler has no idea where to find those procedures that your module’s code is calling, if they don’t belong to the same module/service program.
