I'm seeking out once more to grok IBM i messages, especially QMHSNDPM/QMHRCVPM. There are a lot of examples to be found by Google but those examples always assume context with some actual program implementation. Also, there is documentation from IBM, which largely assumes being born in the OS/400 world.
Is anyone aware of some writeup, shedding light on the topic from another angle: When someone has UNIX programming experience? This is not necessarily about C but also about ILE RPG. In the end, the programming language shouldn't matter for better understanding. I'm writing to this group because I assume that people programming in C might have a background from other operating systems.
I'm still thinking that IBM i messages are a bit like UNIX signals, but much more extensive. Opinions are welcome.
Also, the description of real world use cases for exchanging messages between applications might help to understand. Things I've found with Google also were rather complex and way too theoretical for my brain to digest. ;-)
