Not to mention "long" and "short". Also, yes, PL/I had a POINTER type, but just one. Algol 68 did what languages do now, i.e. specifies the type of thing the pointer points at (or the type of the thing the REF type references; speaking of Algol 68 vocabulary, "dereference" made it into common CS jargon).

Yup, I totally forgot "long" and "short". Although I'm not sure that counts as a lesson learned given that C still came up with "double" for what should have been "long float".

Typed pointers were an ALGOL-W thing originally, though.
