Portable Standard Lisp (PSL) is a tail-recursive dynamically bound dialect of Lisp inspired by its predecessor, Standard Lisp and the Portable Lisp Compiler. It was developed by researchers at the University of Utah in 1980, which released PSL 3.1; development was handed over to developers at Hewlett-Packard in 1982 who released PSL 3.3 and up. Portable Standard Lisp was available as a kit containing a screen editor, a compiler, and an interpreter for the 68000 processor architecture, DEC-20s, CRAY-1s, and the VAX architecture (among many others). Today, PSL is mainly developed by and available from Konrad-Zuse-Zentrum für Informationstechnik Berlin. Its main modern use is as underlying language for implementations of Reduce.
