SL5 is a programming language developed for experimental work in generalized pattern matching and high-level data structuring and access mechanisms. This paper describes the procedure mechanism and the conventions for the interpretation of identifiers in SL5. Procedure invocation in SL5 is decomposed into the separate source-language operations of context creation, argument binding and procedure activation, and allows SL5 procedures to be used as recursive functions or coroutines. This decomposition has led to rules for scoping and for the interpretation of identifiers that are different from those found in other programming languages. Several examples of SL5 procedures are given, including a scanner based on the coroutine model of pattern matching.
