LOGO not Logo? I was looking for a logo.

  Has the programming language Logo even been spelt "LOGO"? I don't recall any such thing.

    Wikipedia seems to suggest a bunch of versions of it were called LOGO, but as its not an acronym I think it probably makes little sense.

    When I was working at BBN in 1978, in part on a LOGO project, the official spelling was in CAPS. Don't forget, in those days, a lot of devices were upper-case only. Hence, even in the 1970s, many people said `FORTRAN' and `COBOL'.

      True, I forgot it was created on a upper-case-only PDP. It's just that I never saw this spelling in literature, even in the 1980s.

        No PDP was upper-case only. Even the PDP-1 with its FIODEC character set had lower-case. Many early output devices were upper-case only.

    I think it is just a matter of which presentations you remember the best. In the video below, there are a couple of places where it is all caps. I'm not sure I recall anything not in all caps on a Commodore 64. Not that I spent much time on one, but it was pretty much my only exposure to Logo. https://youtu.be/Nv5jl1l909s?t=366 https://youtu.be/Nv5jl1l909s?t=366 https://youtu.be/Nv5jl1l909s?t=402 https://youtu.be/Nv5jl1l909s?t=402

      The book in that video clearly calls it "Logo", not LOGO: https://youtu.be/Nv5jl1l909s?t=377 https://youtu.be/Nv5jl1l909s?t=377

    The only implementations I ever used, PDP-10 and Atari 800 only had upper case so it had to be written LOGO. Like ARPANET, in those case insensitive days we really didn’t think about it. Multics was case-sensitive, and it felt weird.

You can get the PDP-11/45 Logo manual here: https://dspace.mit.edu/handle/1721.1/6226 https://dspace.mit.edu/handle/1721.1/6226
