If you’re diving into the world of IBM i programming and stumbled across the term ERRHDLR, you might be scratching your head wondering what it is. I was playing with an SQL Data Encryption routine earlier today and saw a code sample referencing ERRHDLR. “What is that?” I thought. After much time digging through the …
Ditching the Dinosaur Files: Why Your Modern RPG Source Code Deserves a Swanky IFS Pad Instead of Those Crusty Old AS/400 Source Files Ahoy, fellow IBM i adventurers! If you’ve been lurking in the shadowy realms of AS/400 development long enough, you know the drill: punching code into those venerable source physical files like QRPGSRC …
How to Check Whether a Subsystem Is Active in IBM i Using CL If you’ve spent any time automating operations on IBM i, you’ve probably bumped into this classic requirement: “Before I run this job, I need to know whether a subsystem is active.” It sounds simple, but depending on your tooling and IBM i …
Every IBM i developer has opened a source member, stared at a sea of cryptic variable names, and muttered something unprintable. We have all inherited codebases where X1, CUSTFLG, and TMP123 roam free like wild animals. And while that might have been acceptable in the 1980s, modern RPGLE deserves modern readability. A clean naming convention …
If you’re still storing all your RPG, CL, and SQL source in traditional QSYS libraries, you’re missing out on one of the biggest productivity boosts available on IBM i today. The Integrated File System (IFS) is no longer just “that Unix-like thing over there” it’s the natural home for modern IBM i Source Code. Twenty …
If you’ve ever stared at a wall of fixed-format RPG code and thought, “This looks like it was written by a medieval monk with a ruler and quill,” then welcome to my world. I’ve spent far too many hours squinting at columns, indicators, and op codes that look like they were designed to test patience …
Welcome to the latest chapter of my IBM i RPGLE Operation Codes Guide. In my ongoing mission to document and clarify the wonderful IBM RPGLE language for new programmers, students and established old-school programmers looking for new styles of code (who says old dogs cant learn new tricks?!) I’m taking the IBM RPG Operation Codes …
I was in a meeting with a client earlier today – they were discussing hardware changes, software version control, promotion flow and how to set TURNOVER ALM up. A mix of folks in attendance; a couple of current IBM-i programmers, some old AS400 techies and a host of vocal application managers, with everyone seemingly confused …
I’ve spent decades wrangling RPG code on AS400, iSERIES and IBM i systems. You know the drill: endless source files, green screens, and that nagging pull to modernize without breaking everything. Very repetetive and prone to broken code because of a finger slip, a mistyped line of code or a fat-finger moment on the keyboard. …
IBM i SQL Stored Procedures are the King of the IBM i Database Jungle Welcome to a deep dive into the world of database management! Today, we’re focusing on a powerful tool that can transform how you handle data: stored procedures. Whether you’re working with IBM i, SQL Server, or another database system, stored procedures …
In the ever-evolving world of programming, some languages stand the test of time by blending reliability with innovation. RPGLE (RPG for ILE, or Integrated Language Environment) is one such language, particularly for IBM i developers who have evolved through the older generations of this machine (AS/400 and iSERIES). Originally introduced to modernize the classic RPG, …
Welcome back, fellow *cough* AS400 code wranglers and green-screen survivors! If your IBM i source files are starting to look like that one drawer in your desk where cables go to die, it’s time for a tidy-up. Today, we’re diving into how Visual Studio Code can turn your RPGLE and COBOL chaos into something resembling …
