Now we're tackling reworking another large system to be deployed via
VARPG and again and again we find so many benefits to using it (the
biggest one being screen real-estate). Now, I guess that'd be the same if we went C++ or Java, but the difference is that we already know RPG. Learning the nuances of VARPG for a RPG developer is no where near the road of learning a new language.
I know Claus has already mentioned that IBM Support can be used for VARPG issues (and I also read the comment about a PMR that was open for 8 months and not resolved -- I had a PMR open for over 14 months that was never resolved, but it wasn't for VARPG; sometimes it happens.)
It's hard to pin down the value of having IBM support behind a product. (Even if their record isn't perfect.)
And the move to event-driven programming is no small leap to make for procedural programmers. VARPG gives both a GUI IDE and event-driven programming, but the language is at least recognizable. VARPG doesn't require that significant business-logic be coded in it. It can be used almost purely for presentation if that's what's wanted.
My first VARPG app years ago was a simple desktop calendar that I could click days in order to maintain a trivial to-do list. Useful? Not really. But I learned how to use various parts, how to act on events, how to manage parent- and child-windows, how to do just about everything simply to work in the product. Took most of the day.
