When you look at your Original Program Model (OPM) programs and think about why these programs were developed, the goal was likely to provide comprehensive software that would withstand the test of time and produce solid, reliable results as the backbone for business-critical operations. If you were to focus solely on this aspect, you might not see the need to even bother using ILE. After all, you have a programming language that works, it has been around for a very long time, and it is easy to understand. So, let's consider some of the limitations of this way of programming and define the reasons why modernization of the code is necessary.

The past several articles in this column have been related to detecting and managing messages that have been sent to other jobs on the system. We looked at handling message watches, validating inquiry message responses, and providing responses to inquiry messages. Today, we will continue looking at messages but turn inward. This article will review some of the approaches available to handle message conditions that exist within the current application program.
