Landin seems to use the term "abstract object language" for what we would call a "core language" today, which he used to decribe Algol "from first principles"; this is not the same thing as "object-oriented".
- dleeftink 3y agoTrue, but the closure concept does appear alongside it. Are you chasing the etymological or conceptual origin of the phrase?
- Rochus 3y agoA closure is a separate concept from OO; you can have OO languages with or without closures. I am looking for the first CS publication that literally used the term "object-oriented". The conceptual origin of OO is well known and documented in CS literature.
