Having completed a period of mourning it is time to resume the updating of my computer articles. Several new issues in the series on "An Alphabet of Computer Languages" have appeared in the intervening months. Also there are several articles in the magazine during the past two years for which I have yet to add entries.
The June issue covers the language Lisp which like Fortran is one of the earliest computer languages. The article may be reached from the following link:
