This book constitutes the refereed proceedings of the 5th International Symposium on Functional and Logic Programming, FLOPS 2001, held in Tokyo, Japan in March 2001.The 21 revised full papers presented together with three invited papers were carefully reviewed and selected from 40 submissions. The book offers topical sections on functional programming, logic programming, functional logic programming, types, program analysis and transformation, and Lambda calculus.

This volume constitutes the refereed proceedings of the 9th International Symposium on Programming Languages, Implementations, Logics and Programs, PLILP '97, held in Southampton, UK, in September 1997, including a special track on Declarative Programming in Education.
The volume presents 25 revised full papers selected from 68 submissions. Also included are one invited paper and three posters. The papers are devoted to exploring the relation between implementation techniques, the logic of the languages, and the use of the languages in construcing real programs. Topics of interest include implementation of declarative concepts, integration of paradigms, program analysis and transformation, programming environments, executable specifications, reasoning about language constructs, etc.
