Thanks for the information --G.Brougnard (talk) 09:02, 16 June 2015 (UTC)


I twice attributed your name   (for the real nifty idea of using the differences of two 5th powers to help eliminate solutions)   for the Rosetta Code task   Euler's sum of powers conjecture.

If you don't wish to have your name mentioned in this public forum, let me know and I'll remove the references.   -- Gerard Schildberger (talk) 23:06, 26 June 2015 (UTC)

No PB and merci . FYI I used to code in HPL (a long time ago). HPL was used to deliver the Level 64 Bull (Honeywell-Bull) series.--G.Brougnard (talk) 10:30, 27 June 2015 (UTC)


Is that the same HPL that I knew in 1969 or so (while I was working for Honeywell)?   Honeywell Programming Language   was a dialect of   PL/I.   -- Gerard Schildberger (talk) 17:21, 27 June 2015 (UTC)

Yes indeed. I was working with Bull around 1969, and Bull and Honeywell had a common project (internal code P-series, if I remember, the mass storage controller ( 256 Mo disks ...) was built by Honeywell), which ultimately led to the Level-64 Bull series, which were IBM/360-like computers.

I was part of the Honeywell team that built the   BPL   compiler   (Basic Programming Language, a PL/I subset), which in turn, led to the start of the HPL project.

Quite a bit of the BPL compiler was originally written or re-written by Nippon Electric (Japan);   Honeywell had some sort of agreement with that company to provide a PL/I subset compiler for them.

As I recall, the HPL language was going to be a rather ambitious project, the HPL language specifications were driven by the (new and forward-thinking but never built Honeywell computer) architecture hardware operation codes, or maybe it was the other way around.   That new computer would use HPL-like operation codes (opcodes), so it "spoke" native HPL code (or the HPL language spoke the new computer's opcodes).   That new Honeywell computer, as far as I could ascertain, resembled IBM's   FS   (Future Systems)   in some respects.

The BPL compiler was written in BPL and was designed to execute on the Honeywell 200 series (the 1200, 2200, 3200, and 4200 models), all which were IBM 1401 compatible.   The BPL team was based in Waltham, Massachusetts (on the famed computer-belt 128 route), which I joined during the summer of 1969.   I left Honeywell shortly before the BPL team was disbanded (I think in 1970 or 1971).   As far as I knew (at that time), the HPL project never got off the ground ... but obviously, it did.   Possibly, the BPL team became the HPL team.   -- Gerard Schildberger (talk) 20:25, 27 June 2015 (UTC)

Yes! and a lot of (historical) information here : GCOS64 . See programming languages . HPL was released to customers as GPL. I remember people speaking of the Waltham team, and made a short (work) trip to Lexington (?), on the 128 route. It was around 1972. "Le monde est petit", as we say. Nice to meet a - nearly - co-worker, after 40 years ... --G.Brougnard (talk) 11:00, 28 June 2015 (UTC)
