I'm a Ruby programmer and need to learn RPG IV because of my current project. I want to learn primitive types, data structures, control flows, architecture etc. Online resources are as good as paper books.

What book or online tutorial should I start with?

  • What specifically do you need to learn? There are a TON of resources online where you don't really need to invest in a book. – Mike Wills May 24 '11 at 18:36
  • I'm not sure. But, I guess I want to learn primitive types, data structures, control flows, architecture etc. Online resources is as good as paper books. I'll edit the question. –  May 24 '11 at 19:25

This Red Book from IBM is still quite relevant today.

IBM i Information Center is the source for the actual documentation.

RPG-L is a great mailing list with hundreds of helpful people to answer all of your questions.

Another link I knew was out there, but couldn't find at first was from Scott Klement who is well known in the IBM i community.

You can run JRuby natively on the iSeries if that's your primary skill set.

There may be some pushback if you have some stodgy graybeards that are afraid of new technology stacks.
