PS-algol is an orthogonally persistent programming language.^[1]^[2]

PS-algol was an extension of the language S-algol implemented by the University of St Andrews and the University of Edinburgh, Scotland. S-algol was designed by Ron Morrison and extended by Pete Bailey, Fred Brown, Paul Cockshott, Ken Chisholm, and Al Dearle. These extensions were additional standard functions that provide a persistent heap that survives termination of PS-algol programs.

PS-algol was the world's first fully implemented persistent programming language,^[3] and had many users both in academia and, notably, in International Computers Limited (ICL) research labs.^[4]^[5]
