In fact most (if not all) CDC supplied programs use keyword parameters, and have since at least 1971 (the first time I used a CDC6400). 2) A number of object oriented languages such as Smalltalk and EDL allow this form of parameter passing. The original version of the PROSYS user interface prototyping system (essentially a programming environment for EDL) prompted the user for parameters whenever an object was created. The new version of PROSYS will have a graphical editor that will provide an even nicer environment. Details on both EDL and PROSYS can be found in the Graphics Interface'82 proceedings.
