In article <4024@skye.ed.ac.uk> I gave a random number generator which I
attributed to Richard O'Keefe.  I have since received the following
letter about its authorship:

$ Dear Ken,
$ The `clever' random number generator you have in Prolog using
$ three primes is due to ID Hill (david) and myself. See
$ An efficient and portable pseudo-random number generator.
$ Applied Stats. AS183. 1982. Also Byte March 1987.
$ 
$ Please add this reference to the documentation, otherwise people
$ will be confused by the `cleverness' !!!
$ Brian Wichmann.
