My graduate work was in programming by example, also called programming by demonstration. In particular, I was interested in end-user programming and programming in the user interface.
My 1984 PhD thesis, Programming by Example (PDF) (HTML), describes PBE in a simulation of the Xerox Star office system. The system I built was called SmallStar, and was written in Smalltalk. I have the original source code and am very slowly trying to revive it.
While at Xerox, I made a 13-minute video demonstrating SmallStar and programming by example . Watch it here (reproduced by permission). Its quality reflects the video recording technology available at the time.
SmallStar is also described in Chapter 5 of the 1993 MIT Press book Watch What I Do: Programming by Demonstration, edited by Allen Cypher, and co-edited by me and several other people. The entire book is available online.
I am the original author of the UNIX more command (ca. 1978). Here's a short history of how it came to be written.
