This volume contains the papers presented at the latest Glasgow Workshop on Functional Programming, held in Ayr, Scotland, 6-8 July 1992. These workshops have been held annually by the Glasgow Functional Programming group since 1988. Despite the obvious advantages of functional programming, there are still several unresolved research issues which prevent it from reaching its full potential. The workshops provide an opportunity for the investigation of these issues, and for the presentation of current research work. They also allow in-depth discussion between members of the group and invited contributors from industry and other institutions. The papers presented at the workshop concentrated on the design and implementation of functional programming languages, including profiling, compiling, and extensions to Haskell. Other papers addressed the related issues of program derivation and formal reasoning. Among the specific topics covered in this volume are: naturally embedded query languages; a framework for program analysis of logics; analyzing functions by projection-based backward abstraction; compile-time optimization of storage utilization for lazy first order functional programs; a relational derivation of a functional program; programming with conductor classes; avoiding unnecessary updates; LZW compression in Haskell; program transformation in the Glasgow Haskell compiler; formulating Haskell. Functional Programming, Glasgow 1992 provides an upto-date cross-section of the latest work on functional programming. It will be of interest to postgraduate students, researchers and practitioners involved in both practical and theoretical aspects of the subject.
