This research involves the construction of a programming system, HASKEU, to support end-user programming in a purely functional programming language. An end-user programmer is someone who may program a computer to get their job done, but has no interest in becoming a computer programmer. A purely functional programming language is one that does not require the expression of statement sequencing...

A search of the web reveals that natural language is considered to be language which a human would consider natural and unnatural language is language a human would consider artificial. This clearly raises interpretation questions and plenty of leeway so I am going to take the latter view here and bend it somewhat to consider programming languages as particularly good examples of unnatural lang...

Jeffrey D. Ullman and Alfred V. Aho are recipients of the 2020 ACM A.M. Turing award. They were recognized for creating fundamental algorithms theory underlying programming language implementation synthesizing these results those others in their highly influential books, which educated generations computer scientists.
