Introduction to Win32 API Programming with VARPG
by Shannon O'Donnell
Visual Basic and Visual C++ programmers have known for years that to get the most functionality out of their applications, sometimes they had to dip down into the bare metal and access the Microsoft Windows APIs that make up the core operating system. As you develop more and more applications with VisualAge for RPG, you may also discover that there are certain features that you need that can only be obtained by going to the metal. READ MORE >

Accessing External Data Using DB2 UDB DataLinks
by Kevin Vandever
We who program on the iSeries tend to be isolationists when it comes to our data. We store what we need for our applications, and nothing more. If there is desired data in the outside world, we usually attempt to replicate it locally, instead of figuring out how to access it remotely. Well, with DB2 UDB on the iSeries, we now have the capability to pull our heads out of the sand and check out the data the rest of the world has to offer. READ MORE >

Qshell Functions
by Ted Holt
Most computer languages have some sort of subroutine structure. RPG has subroutines and subprocedures. COBOL has paragraphs. FORTRAN and Visual Basic have functions and subroutines. C and Java have functions only. And on it goes. The Qshell scripting language, which runs under OS/400, also allows for internal functions. In this article, I'm going to show you how to write and use functions in Qshell scripts. READ MORE >

Sed, the Stream Editor
by Ted Holt
You're probably familiar with text editors such as SEU, which runs under OS/400, or Notepad, which comes with Microsoft Windows. These are interactive editors. They let you load a file into memory and make changes to it. But there is another type of editor, called a non-interactive editor or a stream editor, that applies a list of commands to a file in order to update it. Though stream editors are not used nearly as much as interactive ones, they can come in quite handy. READ MORE >

Back to Basics: Multiple Subfiles on One Screen
by Kevin Vandever
Yeah, I know. Subfiles have been around for over 20 years, and everyone who programs on the AS/400 should know how to implement them, right? Well, I find that just isn't the case. Some programmers are never exposed to subfiles or they code them so infrequently that they forget what they did. So I am going back to the basics in this article to provide you with a fundamental but practical application that employs multiple subfiles on a single screen. READ MORE >
