The SAPL Interpreter

Sapl is an intermediate lazy functional language.
The Clean compiler has a Sapl code generator integrated in its back-end.
Sapl is aimed at using Lazy Functional Programming Languages at the client side of web-applications.
For this, two execution platforms for Sapl exist. A Java Applet version and a JavaScript version.

Sapl is based on a pure graph-reduction machine that can also be used for executing lambda-calculus expressions.
The following lambda-expression is a closed formula for generating prime numbers using Eratosthenes sieve:


A more readable version of it can be run using the following interpreter:
