RPG is not a Rocket Propelled Grenade
RPG2 is that Logic Cycle Thing
RPG3 is the System/38 version
RPG400 is the revamped RPG3 that came with AS400
everything after that is RPG... unless its ILE then its RPGLE or sometimes RPG4, or its free format so its RPGLE /Free... or its SQL so its RPGSQL or SQLRPGLE... or as many people call RPG/Free - RPG FIVE..... aaaargh
Why doesn't IBM just have a simple version number for each iteration of the wonderful IBM RPG programming language?
IBM i 7.1 Technology Release 7
I love the enhancements to RPG with IBM i V7.1.7. RPG finally looks and reads like a normal modern language. With the advent of this latest version of IBM i, RPG has been neatly upgraded to be a fully free format language. This is a long overdue and a significant change to the language itself.
