Pop-11
Robin POPplestone, 1975. Originally for the {PDP-11}. 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.
