COWSEL programming language

COWSEL is the COntrolled Working SpacE Language. Between 1964 and 1966, it was designed and implemented by Robin Popplestone, initially on a Ferranti Pegasus computer at the University of Leeds and on a Stantec Zebra at the Bradford Institute of Technology; later with Rod Burstall on an Elliot 4120 at the University of Edinburgh. It was based on a reverse Polish form of Lisp combined with some ideas from CPL. In the summer of 1966 it was renamed POP-1 and development continued under that name.
