Many thanks. I can give "(go)" in the interactions window and it works.
But to load serve.rkt I had to navigate to its folder.
I have not been able to find a succinct description how to cope with the
Windows directory
system to make Racket find user-created files, either to run them as
programs or open them
as data sources or destinations. Perhaps there is a particular directory
where they have to be
for Racket to find them, and this can be set as a default in some way
(environment variable
or whatever).

Ah, wonderful! This helps enormously.
Ok, so I see that you're on Windows, and that you're doing these
interactions through DrRacket.
Note that the Systems Guide is done in the perspective of someone
who'se _not_ in DrRacket, so some of the confusion is due to that. In
your case, I would _strongly_ recommend ignoring the guide's request
to use enter!, xrepl, readline, etc.
Instead, just open serve.rkt in DrRacket, and Run it.
As you modify serve.rkt, just Run the program again when the guide
prompts you to use enter!
For example, when the systems guide says something like:
> (enter! "serve.rkt")
[re-loading serve.rkt]
> (serve 8080)
at this point, press the Run button in DrRacket, and then execute the
following command in the Interactions window:
(serve 8080)
Let us know if this helps.
