Join This IBM i Community!

It’s July 2020 and time to upgrade this website to something more than just a blog. It’s time to give something back to the wonderful IBM i Community that I’ve enjoyed for so long:

Just who is this bloke?

Nick Litten – AS400 iSeries and IBM i Consultant Nerd.

I’m an IT Consultant and IBM i Software Developer (aka RPG Programmer) primarily working on IBM Power Systems (IBM i, System-i, iSeries, AS400). Thirty years ago (damn that makes me feel even older than I am) I fell into computer programming as a career. Tapping on these IBM keyboards has taken me around the world, and I’ve now settled in sunny Nevada USA. It’s a terrific ride. I believe us older experienced programmers have a responsibility to share the knowledge and help the *freshers* who are stepping foot in the IBM i pond for the first time.

English sounding RPG Hippie that looks exactly like me

I started back in the days of IBM System/38 machines, the IBM PC XT was just being conceived, APPLE was working on its APPLE 2E, the internet was a futuristic dream and dialup Bulletin Boards were leading edge social media.

My home computer was an IBM PC XT with a modem the size of a shoe box that I plugged into my parents phone line, after disconnecting the bakelite rotary phone.

Working on IBM mainframe/midrange systems has taken me around the world, earning a good salary and, most importantly, doing something that I have really come to love: RPG is a fantastic language, IBM i is a terrific operating system and the hardware is second to none.

My blog is an attempt at sharing the IBM i Love, highlighting some programming techniques and sometimes just waffling about personal lifestyle nonsense.

If you are looking for some professional help, please reach out to me.

If you are looking for some programming or technical tips then get searching.

If you are just here to enjoy to waffle then read on my friend 🙂

Which 5250 Screen Emulator shall I use?
The IBM i System, like its predecessors the AS400 and iSeries, uses something called 5250 to stream its data to a terminal, often called a green screen. You’ve seen these clunky old terminals in black and white sci-fi movies. We still use them… sort of… we use terminal emulators (software that emulates the functions of those old terminals) to type commands into a command-line interface using windows/linux/mac whatever.

So which one is best?

How do we start our modernization project?

The driving idea behind modernizing a legacy IBM AS400 or iSeries application is much more than the simple task of refactoring our old RPG and CLP codebase.
