That sounds a lot like the printout shown in an article in Computer Games I,
edited by David Levy--bad print quality, short variable names, etc.. It's in
Pascal too. The article is called "Creating a Chess Player", and it's by Frey
and Atkin. It says this in the text:
"CHESS 0.5 is a program written in Pascal by Larry Atckin, who is
coauthor with David Slate of the world championship computer chess
program CHESS 4.6."
So I guess it's not quite CHESS 4.5... There is also a BYTE article with (as
I recall) a similarly bad print quality (looks like a bad photocopy of an old
printout) which may also by by Atkin, but I don't remember that clearly, and
I can't get at my BYTEs very easily...
