The API allows processors to navigate from class declarations to corresponding types with specific type arguments and vice-versa. Scripting is often contrasted with system programming, as in Ousterhout's dichotomy or "programming in the large and programming in the small".In this view, scripting is glue code, connecting software components, and a language specialized for this purpose is a glue language.Pipelines and shell scripting are archetypal examples of glue languages, and Perl was Batch input sessions are stored in the database as database tables and can be used within a program as internal tables when accessing transactions.
