Talk:Actor (programming language)

Actor User's Manual
I used the Actor programming system in its time. It was the precursor of Object Oriented programming in Windows that lead to industrial strength OO systems like Turbo Pascal 5.5. I still have the original User manuals, but they don't have a ISBN number. How does one reference them? Juanco (talk) 22:12, 7 December 2010 (UTC)
