Vax prolog interpreter

[ucsbcsl!eggert at Berkeley]

I have transported Clocksin and Mellish's PDP-11 Prolog interpreter to
the VAX.  Its main advantage is for teaching: it is covered by their
introductory text (Programming in Prolog, Springer-Verlag, 1981), and
is somewhat compatible with Edinburgh DEC-10 Prolog.  Its main
disadvantage is that it runs slowly and has internal memory
limitations: it is not suited for much practical work.  My
modifications to their system (and to some Berkeley Unix code) are
gratis, but you must obtain permission from the original authors and
send a copy of their letter to me.  Write to

Chris has recently moved to the University of Sussex; I don't have his new
address, but the above should serve.
