L. E. McMahon; L. L. Cherry; R. Morris. Statistical text processing. The Bell System Technical Journal, 57(6):2137-2154, July-Aug. 1978. DOI: 10.1002/j.1538-7305.1978.tb02146.x You can find it openly available online at: https://archive.org/details/bstj57-6-2137/mode/2up The article was part of an amazing special issue of BSTJ devoted to Unix. A second such issue, 63(8) was published on October 1984. In the late 1980s both issues were also sold as books by Prentice Hall under the title "UNIX System Readings and Applications". I broke the bank buying them as a student, but didn't regret it. Diomidis - https://www.spinellis.gr On 16-Feb-22 2:09, George Michaelson wrote: > The trigraph spelling checker sounds wonderful.
