Description
Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. COWSEL
(COntrolled Working SpacE Language) is a programming language designed
between 1964 and 1966 by Robin Popplestone. It was based on a RPN form
of Lisp combined with some ideas from CPL. COWSEL was initially
implemented on a Ferranti Pegasus computer at the University of Leeds
and on a Stantec Zebra at the Bradford Institute of Technology; later,
Rod Burstall implemented it on an Elliot 4120 at the University of
Edinburgh. COWSEL was renamed POP-1 during the summer of 1966 and
development continued under that name from then on.
