I went out searching and thought I had found an answer in the archives, but I see it was authored by you, so it must not have been entirely satisfactory:

I also saw the suggestion from Koenker. The current holder of the rights to the S language (at least on PC's)  would be TIBCO. They do list the acronym `hpgl` on one page in the S+ documentation, but it is in the "deprecated functions" section (p 39):

Good luck.
