Bob 1.0 Users Bugged By Lack Of One Feature
The launch of the Bob AI coding tool in late March has been met with considerable amount of hoopla by IBM, as well as anticipation by the IBM i community. The early reception to Bob has been mixed, due in part to the lack of one particular feature.

Guru: Cohesion First – What A Procedure Should Be Responsible For
One of the easiest mistakes to make in procedure-driven RPG is assuming that small procedures are automatically well-designed procedures. They are not. Size and cohesion are related, but they are not the same thing. A cohesive procedure has a single, clear responsibility. It exists to answer one business question or perform one business action. When a procedure tries to do more than that, it stops being a reusable building block and starts becoming a liability.
In procedural RPG, nothing enforces this discipline. There is no compiler warning when a procedure quietly takes on a second responsibility. There is no language …
