I read this with fascination in 1967 or perhaps early 1968. It was almost current then! Looking at it now, I still remember some of the phrases. <https://www.computer.org/web/csdl/index/-/csdl/proceedings/afips/1964/5064/00/50640001.pdf> (I was in high school then and it was extremely difficult to get information about computers then. The internet is such a great facility! I used to sneak into U of T, Waterloo, and York to get accesss to computers.) It's fun to read of Algol's support for recursion and dynamic memory allocation of local variables: it is fair to say that they are difficult, and their inclusion in an Algebraic lanuage that is intended to be universal is controversial. How far have we come! (How did I end up on this page? I posted a link to the Algol 60 report to the list. The report is dedicated to the memory of William Turanski who was killed before the conference. I've always wondered who he was. It turns out that he worked with Anatol Holt on an early programming system for the US military. He also was a Putnam Fellow (undergrad math contest). Turanski is mentioned in Rosen's paper.)
