While tidying up my bookshelf I found an old copy of "Time-Shared Computer Languages" which discussed a bunch of languages available on-line in 1973. One of them was JOSS, first implemented on the vacuum tube Johnniac, then reimplemented on the PDP-6, and available on the PDP-10 where DEC called it AID. A cut down version was available on the PDP-8 as FOCAL. I think it had a lot of influence on Basic, both in that program lines were numbered and statements started with keywords like Let. The numerically inclined admired its correctly rounded ten digit decimal arithmetic, so sqrt(3)*sqrt(3) was 3, not 2.9999999999996. Are there any versions of JOSS still around? I suppose I could fire up a PDP-10 simulator and look for a copy of AID but I was hoping for something less retro. -- Regards, John Levine, jo...@iecc.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly

One thing about JOSS is that (unlike FOCAL, which was conventional in using normal binary floating-point in software, like most versions of BASIC) it used a binary power of ten exponent with a binary integer mantissa. Like Intel processors use today for decimal floating-point.

I'd like to see that also. I think one of the systems at the LCM has it, don't know if they have source, but I haven't had time to re-learn enough TOPS-10 or TOPS-20 to check it out. -- Pete

The Dec manual for FOCAL said it was inspired by JOSS, not that it was a version of JOSS.

The Defense Technical Information Center (DTIC) at http://www.dtic.mil/dtic/ has a lot of detailed information on JOSS. For example ... JOSS: ASSEMBLY LISTING OF THE SUPERVISOR http://www.dtic.mil/docs/citations/AD0660836 I would not be surprised if JOSS could be resurrected in an emulator, if somebody felt so inclined (and I do not).

Huh. I found it on the RAND web site. It's a 170 page PDP-6 assembler listing. It looks like it ran on the bare machine, not under the DEC monitor. -- Regards, John Levine, jo...@iecc.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly
