Programming languages are the material from which every software product is built.
Europe has great strength in programming language research, with many world leaders both in semantic theory and in implementation. The purpose of the WG is to bring these researchers together, with the specific aim of improving the communication between theoreticians and practitioners, and between people with different expertise. In this way we wish to focus theoreticians' attention on important practical problems as well as to speed up the application of new theoretical ideas in practice. Time will be allocated also for discussion.
