As I recall, the original definition of ASCII
suggested that the
LF character was either "line feed" or "new line", and that if it
*was* new-line, it would be stand-alone.
I have put a copy of the original ASCII standard (scanned images) at
http://www.cogsci.ed.ac.uk/~richard/ascii.tar
I don't remember where I got it from.

This does not appear to say anything about LF vs "Newline" (as either a
name or a function), though the 1986 version of ASCII deprecates it, so
was most likely acknowledged in versions between these in response to
practices on OSes such as Multics. ECMA-6:1973 acknowledges it, for
example (the fourth edition at
https://www.ecma-international.org/publications/standards/Ecma-006-arch.htm).

I have a book here called _Coded Character Sets, History and Development_ (C.E. Mackenzie,
1980, Addison-Wesley) that is a wealth of info.
According to that book, the early 60s military codes were 7-bit, not 8-bit. Maybe Jennings
is referring to a later standard?
The only reference I can find to a ‘DoD standard’ is this:
During the early 1960s, a different kind of solution
was tried in the Department of Defense. Recognizing that 42 graphics — 26 alphabetics, 10
numerics, and 6 specials (period, comma, slash, asterisk, minus sign, and dollar sign) —
were common to all trains/chains, an edict was issued that only these 42 graphics could be
used on reports. […] (p. 420)

Or maybe it was a 7-bit code with a parity bit and they're counting it
as 8-bit.

I found a pre-ASCII standard proposal at
https://archive.org/details/enf-ascii-1961-09 that refers to
"MIL-STD-188A". Googling *that* finds stuff referring to Fieldata, so
that's probably what it's referring to. Fieldata does have a
"Special"
control character immediately before DEL. And now that I check again,
the WPS page does say "For all intents and purposes "FIELDATA" today
refers to the character code. It, or a minor variant, is sometimes
called the "DoD standard 8-bit code".
