To be honest, I don't recall when I was told about Socialist ALGOL; to the best of my knowledge, it was somebody at one of the ALGOL 68 workshops that were held back then, but I can't recall who. And I suspect that the official name of this dialect would not have been “Socialist ALGOL” anyway. The idea was that it would unify all the ALGOL 60 dialects in use around the east bloc. (And yes, I'm familiar with the saying that if you replace n ways of doing the same thing with one, you end up with n+1 ways of doing the same thing.)
