A customer showed me their internal system yesterday.
It runs on an IBM AS/400 and it's written in IBM RPG.
RPG was originally developed in 1959, but the latest stable version is from 2020.
I must say it looks surprisingly modern: Coding in RPG IV - a beginner's tutorial[^]
Not sure if that's also the version of RPG that their software is programmed in, but I'm guessing it isn't as it's 40-something years old.
Other than that it looks like a fancy DOS program (colored letters on a white background, so no retro black/green, and completely keyboard driven, although mouse works too).
Apparently, they've been trying to replace it for 25 years, but without much success.
Meanwhile it's still actively being developed and their supplier has a development team just for this client (all other customers switched to the newer version of the product).
My client is now looking into buying the entire product just so they can keep using it 
They could buy the product, but the programmers are of course in no way obliged to move with the software.
My guess is they'll HAVE TO replace it in the coming ten years or so and it would be better to start working on a replacement NOW rather than buy something that's already obsolete.
But just out of curiosity, how many here worked on RPG and how many still do, could and/or want to?

I have worked for a short period on a IBM S/36 with RPG II some 30 odd years ago.
Forgot all about it besides the fact that it looked a lot like assembler and after checking your link doesn't even remotely resemble RPG IV.
After some 4 months I switched to the client side development which was done in Clipper 5 synchronising data with the S/36.

Camera SVG rendered to PNG[^]
This is my current render of the final test document for my initial round of tests. It's got many complicated overlapping, semi-transparent gradients all xlink:href'd together.
It's not quite as fast as I'd like, because I traded away speed to dramatically reduce memory usage and increase flexibility, but it should be fast enough for small renders, which is what it's primarily meant for.
I still have more to do but it's basically just mop up at this point, with the largest task being to implement some baseline CSS support (selectors for classes and ids only so I don't need a DOM)
I'm thrilled.

I'm not going to lie, that's pretty damn impressive. Very nicely done.

Yes, I agree. Very impressive.

Working with an STM32 device and trying to implement program in c++. Every platform is a little different in the way it implements C++ so trying to learn the ins and outs on the STM32.
Been working on a simple Timer singleton class for the past 6 hours and it's been 2 steps forward and 1 back. Should be fairly easy but there were so many gotchas that made it very frustrating.

I'm probably old fashioned, but I don't find C++ that helpful when it comes to embedded work - stick to C and assembler is my preferred route.
The idea of embedded is to get the best performance out of limited resources (speed, memory and / or power) and the extra overhead of class based OOPs isn't necessarily a good idea. And it's way harder to keep an eye on memory management to ensure memory fragmentation doesn't rear its ugly head after 2 weeks of continual runtime ...

I disagree c++, I've used C++ on various platforms for years and never had a problem.
I find; code size comparable, speed acceptable (you can also mix c++ and assembler).
The Arduino platform uses c++ as it's major language and there are libraries for everything under the sun.

Forget classes. template and constexpr mean I can create faster/more efficient code in C++ than you can readily create in C.
You don't have to use features that generate overhead in C++. Zero overhead C++ is a thing.
Besides, Generic Programming > Object Oriented Programming anyway
