POP-11

Robin POPplestone, 1975

Written originally for the PDP-11 computer. In some ways, POP-11 is like FORTH (stack-oriented, extensible, efficient). It's also like LISP (functional, dynamically typed, interactive, garbage-collected). And the syntax is like Pascal (block-structured).

Programming in POP-11, J. Laventhol, Blackwell 1987.
