I’ve been waiting for a simple free-format RPG editor for the longest time. Opensource ILEditor delivers. It’s free, open source, actively maintained and growing in support. It’s quick and simple to use, and I can already see that as it’s popularity grows new functions will be easy to add. #nice The Author is Liam Allen […]

I found this article ages ago and book marked it. I just re-read it and found it just as pertinent today as when it was written 15+ years ago! Tips to reduce static storage The variables in an ILE RPG module or program can be divided into three storage (memory) classes: static, automatic, and heap […]

Or as the grey haired folks would say “How to configure the ISERIES FTP server to use SSL” or as the geriatric brigade would say “making the AS400 talk using that newfangled secure FTP nonsense“.

AKA – writing a new DSPLY opcode that shows more than 52 characters Using the DSPLY opcode to quickly debug a program has long been a staple of us RPG keyboard whackers. The DSPLY operation lets us “display the data in a variable” onto the screen. Everyone uses this quick and dirty technique and everyone […]

AKA Command Line Access from System Request 3 If you are an IBM I software developer or power user – then that headline will make sense.

DevOps helps businesses respond to business, project and market changes quickly and fluidly. I’m not sure if fluidly is a word, but if its not, well, it should be. Devops focuses on many smaller high-quality software updates being rolled to users with a rapid schedule. Using continuous delivery and continuous testing to reduce risk, garner […]

RPG INDICATORS are switches Just like car indicators (or ‘blinkers’ as my American cousins call them) they can be switched *ON or *OFF in a program to indicate the state of a certain piece of logic. In the IBM RPG language, it used to logically flick the switch of a numeric indicator 01-99 to “indicate” […]

I’ve been playing with my home Wifi this week, trying to resurrect my old SCALEO Home Server which has been in deep coma since a brown out a few months ago. But I digress… So, I’ve installed a new router (Linksys WRT03200ACM) which gets mixed reviews but it looks so bloody Funky I just couldn’t […]

What’s new, Ubuntu 18.04 Linux? The biggest change is heralded as the switch from the traditional Ubuntu UNITY DESKTOP in favour of GNOME.

So, we have a customer masterfile that’s been around for years. Users have been keying in customer info and sometimes adding email addresses, sometimes not, sometimes entering nonsense or even just text that says things like “this chap has no email so don’t email him”. Yes, it’s a filthy dirty file filled with grubby email […]

This week I be mainly…. working on a Casino System upgrade, dragging decades old code into the twenty first century. Old RPG3, RPG400, CLP programs and techniques using outdated OPNQRYF and QUERIES are fighting back tooth and nail.

I had to pull records from two files with a matching date value in each file. To make things interesting, the date on one file was stored in timestamp format and the date field in the other file was stored in hundred year date format. SQL (and QUERY400) can very nicely convert dates stored in […]

There are lots of code snippets, example programs and long waffling discussions in internet land filled with pointy headed AS400, iSeries and IBM i programmer chaps (and chappettes) arguing about the best way to “validate an email address in RPG”.

IBM i Authority is a wonderful beast with many layers of complexity.
