'''SISAL''' ('''Streams and Iteration in a Single Assignment Language''') is a [[General-purpose programming language|general-purpose]] [[single assignment]] [[Functional programming|functional]] [[programming language]] with [[strict semantics]], [[implicit parallelism]], and efficient [[Array (data structure)|array]] handling.

SISAL outputs a [[dataflow]] graph in Intermediary Form 1 (IF1). It was derived from the Value-oriented Algorithmic Language (VAL), designed by [[Jack Dennis]], and adds [[recursion]] and finite streams. It has a [[Pascal (programming language)|Pascal]]-like syntax and was designed to be a common [[high-level programming language]] for numerical programs on a variety of [[Multiprocessing|multiprocessor]]s.
