This isn’t even like the worst of it. It’s an old enough language they still thought the compiler shouldn’t have to do more work.

So you have to declare all variables, types, and methods in the top section of the class, and the method implementation in its own section. That means while working on a method, the method signature is a long way away. And because abap developers are allergic to splitting up code into reasonable classes, that can be a couple thousand lines away.

Oh and all classes are in the global namespace. So all the classes you make must start with the letter z because SAP reserves any and all names that don’t start with z.

Oh and they didn’t feel like making library code to do a lot of basic stuff, oh no, they thought that 3000+ keywords was a much better system. Especially sense hovering over a keyword gives no documentation and discoverable is therefore pretty terrible.

Also they wanted everything to be sentenced like so keyword structures are often many special words in specific orders and hopefully you can write enough of it to get a prompt to fill in the rest.
