CPS 343/543 (3 sem hrs) is a course in programming language concepts. The approach involves studying language concepts, such as scope and parameter passing, by implementing a series of interpreters in Scheme, for purposes of its combined simplicity and power, and assessing the differences in the resulting languages. Students can also expect a comparative survey of programming paradigms, including the use of representative languages, such as Haskell, PROLOG, and Smalltalk. The course emphasizes alternative language features such as continuations, currying, and lazy evaluation, and the use of these features in novel application areas such as web interaction management. Course themes include the relationship between languages and the capacity to express ideas about computation, and the influence of language design and implementation options on current trends in programming practice and vice versa. This course assumes no prior experience with Scheme, Haskell, PROLOG, or Smalltalk.
