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.

The previous article of the series discussed module and service program organization. Itâ€™s now time to do the same for binding directories.
Written by Rafael VictĂłria-Pereira
Letâ€™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 moduleâ€™s exports. The moduleâ€™s procedures might call procedures from other service programs; these are the moduleâ€™s imports. The problem is that the compiler has no idea where to find those procedures that your moduleâ€™s code is calling, if they donâ€™t belong to the same module/service program.
