The Address programming language (Russian: Адресный язык программирования Ukrainian: Адресна мова програмування) is one of the world's first high-level programming languages. It was created in 1955 by Kateryna Yushchenko. In particular, the Address programming language made possible indirect addressing and addresses of the highest rank – analogous to pointers. Unlike Fortran and ALGOL 60, APL (Address programming language) supported indirect addressing and addressing of higher ranks. Indirect addressing is a mechanism that appeared in other programming languages much later (1964 – in PL/1).
