Following on from my previous blog (basic email validation) I decided that it would much nicer to (a) have the regex stored in a data area so that we can easily play with it to try different validation scenarios and (b) lets have a shot at a much stricter validation because there is an official […]

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”. I know because I’ve read nearly all of them, as well as tried all the […]

Wow – that’s another long url title. I really wanted to call this “How To Check Out An Object From One Library And Promote It To A Different Library but keep the program source code line change dates” but that just seemed to ridiculously long. Why are we talking about this? We all know there are […]

What’s in a font? Lots of things make our life easier as IBM i Programmers. Working with a clean, easy to read 5250 terminal mode is one of the them. I’m a big fan of Mochasoft terminal emulator, but growing to love the new IBM i ACS (Access Client Solutions) with its multi-tabbed approach to […]

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 […]

Back in the good old days of single megabyte disks the size of a shoebox, when hard drives were called Winchester Drives and the only phones we used were actually used for making telephone calls, size was everything (insert slightly rude joke here). In the daily effort to shave off a byte here and a […]

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 Old RPG3, RPG400, CLP programs and techniques using outdated OPNQRYF and QUERIES are fighting back tooth and nail.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 love this schnizzle. 🙂 One of the techniques for upgrading/converting older QUERY400 reports to modern SQL […]

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 […]

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 […]

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” […]
