SISAL

Designed by: James McGraw

SISAL (Streams and Iteration in a Single Assignment Language) is a general-purpose single assignment functional programming language with strict semantics, implicit parallelism, and efficient array handling.

SISAL outputs a dataflow graph in Intermediary Form 1 (IF1).

It was derived from VAL (Value-oriented Algorithmic Language, designed by Jack Dennis), and adds recursion and finite streams.

It has a Pascal-like syntax and was designed to be a common high-level language for numerical programs on a variety of multiprocessors.
