SET Language. A very high level language based on sets, designed by Jack Schwartz at the Courant Institute in the early 1970s. It was possibly the first use of list comprehension notation.
Data types include sets (unordered collections), tuples (ordered collections) and maps (collections of ordered pairs). Expressions may include quantifiers (‘for each’ and ‘exists’). The first Ada translator was written in SETL.
