More was I curious about the documentation of address
chains in books.
It was even discussed in Lomutu and Lomuto, "A Unix Primer", a pleasant
book whose level is accurately described in the title.

New subject: ed: multiple addresses (with semicolons)
Hoi.

Thanks for the recommendation of this book. I now have a copy and
am looking forward to reading it. It must have been a great book
for users at the time (mainly covers editing and formatting) and
now it looks to be a great book for someone interested in
understanding how the experience of using Unix must have been to
normal users back then.
Although the semicolon address separator is explained in section
10.2.1 (page 143), I couldn't find address chains or supplying
more addresses than necessary to commands mentioned in the book.
Of course, as I haven't fully read it yet, I could have missed it,
although I checked the relevant pages.
Nonetheless, I'm happy with this new (old) book, which I luckily
received in nearly mint condition. :-)

Now I enjoy reading through the book. Thereby I came across this
piece of information (section 7.3.3, p. 87):
(Historically, f stands for ``facts'', but most people
prefer to think of it as an abbreviation for ``file''.)
Why ``facts''?
The manpage in 1st Edition does not list an f command at all.
The manpage in 3rd Edition explains f as ``the filename command''.
Assember and C sources of various editions all talk about filename
and none about facts.
Neither does ``facts'' seem to come from qed.
I couldn't find an f command there at all.

What's the background for the comment about ``facts''?

What's the background for the comment about

(for DMR's QED for GE-TSS on the GE 635):
_History of QED_
The original QED was implemented at the University of
California, Berkeley [4]. Substantially redesigned versions
were written by the second author (KLT) for the CTSS system
at MIT [1] and in BCPL for MULTICS. The latter version has
also been available under GE-TSS using I/O routines supplied
by A. W. Winikoff.
_This version of QED_
The present incarnation of QED was implemented in GMAP by
the first author (DMR). It offers noticeable improvements
in speed, program size, and text packing density over the
BCPL version, of which it is a direct descendant. New
facilities include a redesigned Global command and a
numerical capability
The F(acts) command appears on page 9 (pdf page 10)
The F command causes QED to type out
1) the number of words on QED's "free list",
2) the highest memory location used for text storage, and
3) the current core allocation.
When the third number gets near 32K, take care not to exceed the core
maximum.
