Systems Programming in the Functional Language FP

The development of systems software in functional programming language is still an open problem.This paper describes a preliminary experiment with systems programming in Backus' FP systems.Itconsists of two systems programs.One is a self-compiler of FP,the other an interpreter of the semantics ofFFP(Formal Functional Programming).Both were implemented on an FP machine——FPM2.Somediscussions are made finally.
