All caps haven't been a part of the language since Ada83, go check the follow up spec, Ada95. Maybe you're thinking of Niklaus Wirth's languages, the Modula's and Oberon?

Wirthian languages seemed to keep the 6bit symbol encoding of the original Pascal, where the symbols and keywords ended up case-nonpreserving. Was that changed at any point with Modula or Oberon? I never have seen any code with all caps.

Oberon is case-sensitive and all keywords are all caps. I was curious to see it because I like Object Pascal/Delphi, that was the most distracting part of the language coming from Delphi standards.

That approach used to be chosen by many languages, because it is the best alternative to syntax highlighting when none is available.

Yeah, it's horrible to see and worse to type. I took Oberon-2's grammar and changed it to a more Ada like one for a project I'm working on.
