What’s the best Free RPG Editor?


Jul 30

If you are reading this blog then chances are you are (a) an RPG Programmer and (b) using SEU to edit your code and (c) you are frustrated that SEU wont syntax check new RPG anymore! It’s time to leap into an RPG EDITOR or be pushed… RDi is bloody good but it’s also a very expensive code editor. I still hope that one day, IBM will release a lightweight, desktop Free RPG Editor?

This begs the question of “which editor should a RPG developer use?” or

What is the best free alternative to RDi (Rational Developer)

Free RPG Editor

SEU’s syntax checking has been frozen at IBM V6 level and, sadly, this means that good old green screen SEU will not recognize any of the 7.1 RPG enhancements and will flag all these new features as errors.

As far as I know SEU has been stabilized by IBM. This is also known as “declared dead and will be given no future updates”. IBM clearly want people to adopt their flagship code editor for IBM i Software Developers — RDi is Rational Developer for i

RDi is an Eclipse based code editor for IBM i Developers used for writing modern RPG, CL, XML, JAVA, PHP etc code. Ten years back we used it’s predecessor called WDSC “WebSphere Development Studio Client”. If you are not using a code editor then your developers are probably stuck with the twenty year old text based code editor SEU “Stoneage Editing Utility” 😉

There are other code editing tools out there ranging from older opensource and freeware solutions to modern commercial products, but IBM’s RDi is by far the best. IMHO

ILEditor – ILEditor is an editor for development of ILE applications on IBM i. ILEditor will support development with any ILE language, be it CL, RPG, COBOL, C or C++. Error listing and syntax highlighting is available for all ILE languages. This is my preferred choice for free RPG editing.

ORION – The latest FREE offering from IBM


Websphere Development Tools – although its free it’s also very old, doesnt support new RPG code and replaced by RDi

RPG Next Gen – I really liked this and used it after WDSC and before moving to RDi. The author has moved to a commercial route, checked out it’s replacement (Mi Workplace)

Paid Alternatives

Mi Workplace – it’s not free but it’s cheap! Consider that Rdi is close to $900 and MiWorkplace is close to $40 – but it’s a full featured editor and priced correctly. If you cant get RDi this is your best best
