I found BCPL quite cool too, except for the verbosity, which, like Pascal, I did not much feel at the time. I read the whole (slim) book about it, by Martin Richards, its creator, and enjoyed it. Good amount of low-level system programming examples in the book, and it all being in a language with only one type (the machine word), made it more fun to me, although (or because) I did not know of higher level programming constructs at the time.

Its history and uses are interesting.
