In Basing Pointer Variables in RPG: The Basics, I wrote about the fundamentals of using basing pointers, a concept I came to understand when I learned Pascal. In this article, I continue my discussion of the use of pointers by showing how to implement linked lists in RPG.

Before I start into the meat of the article, let me first give credit where credit is due. I had pondered the question of building linked lists in RPG for some time, but I had not devised a way

When I start up an interactive SQL session I see “Current connection is to relational database Sxxxxxxx.” Sxxxxxxx is our serial number. Is there a way to change the relational database name to something a little more meaningful?

Use the Work with Relational Database Directory Entry (WRKRDBDIRE) command. The entry you need to change is for remote location *LOCAL. For more information about WRKRDBDIRE, see Using the WRKRDBDIRE command at IBM‘s Info Center.

That solved the problem. It was little scary because I couldn’t change the name, but had to delete the existing one

I once worked for an insurance company that had a 24x7x365 operations staff. When iSeries error messages occurred, the operations staff mostly handled problem resolution and other staff members were rarely alerted. Sadly, this world no longer exists and it is now left to i/OS administrators to detect when system errors occur on a 24×7 basis and to react to them in a timely manner so that production isn’t delayed.

Toward that goal, this week and next, I will describe a basic game plan for managing i/OS error messages so that all system and programming issues are quickly handled without
