This book constitutes the refereed proceedings of the 10th International Symposium on Programming Languages, Implementations, Logics, and Programs, PLILP'98, held jointly with the 6th International Conference on Algebraic and Logic Programming, ALP'98, in Pisa, Italy, in September 1998.
The 26 revised full papers presented were carefully reviewed and selected from a total of 68 submissions. Also included are two invited papers and abstracts of two tutorials. The papers are organized in topical sections on verification, logic programming, static analysis, software methodologies, object oriented programming, term rewriting, functional programming, metaprogramming, optimal evaluation, integration, and constraint solving.

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.
