Thanks much. Yes I know you were speaking of assembly. I was just considering
history. I've always heard binary was first. What that might mean IDK. And
there was no evidence presented for that.

some early calculators that killed slide rules. What kind of "processor" were
they using? I'm not so sure there was real HLL before Adm. Hopper. And no
binary by Babbge. Do you have any links or anything from the '40s?
HLL? I was talking about assembler... Anyway, I don't believe COBOL was the
first HLL, though it certainly was fairly early.
You can find writeups about Harvard Mark 4 in Bitsavers, and presumably other
old stuff as well. My own comment was referring to documents about early Dutch
computer work I've been looking at. For example this one:
http://oai.cwi.nl/oai/asset/9603/9603A.pdf, "Principles of electronic
computers: course February 1948". It mentions that, at time of writing, the
only functioning electronic computer was ENIAC. (That may not be entirely
accurate, considering possible classified machines, but it's certainly close.)
It describes the key components of a computer, and gives an outline of what an
instruction set might look like. No suggestion that the instruction set in
question corresponds to any actual design, though.
Unfortunately it's in Dutch.
