Each IBMi User Knows They Run the Most Efficient System. All Others Just Have Too Much Money. Let's take a moment to ponder this thought-provoking and slightly provocative motto: Each IBMi user knows they run the most efficient system. All others just have too much money. I can't take credit for this line—I read it somewhere a while ago, and unfortunately, I don’t know who the original author is. Nonetheless, it's a statement that resonates with many of us in the IBM i community.  But is this motto still relevant today?

In RPG, we often need to manage strings, split them into substrings, and manipulate them efficiently. The %SPLIT BIF is a powerful and useful tool to handle this task.   But what exactly is %SPLIT? 🤔   %SPLIT divides a string into multiple parts using a specified delimiter.
