David,
I haven't had a chance to dig into daytime yet. My needs are still pretty
minimum and I can still get by with tcpdump. Thanks for introducing me to
daytime nonetheless.
I can't reproduce the "Socket wiping out behavior" I mentioned previously.
I'm letting it go for now. If it reappears and

Indeed, and that's a good reason to say that it doesn't matter very much
if `smalltalk-mode` prettifies `_` or no

To be fair, nor does it define "_" or "^". All it says was "left arrow" or
"uparrow". We got to make do with what we have.

Sorry but I didn't write or submit the patch. I think Stefan Monnier wrote it.
Initially I liked the idea of a pretty-print filter,
but I'm not so sure any longer.
It may complicate things; perhaps it's not such a good idea to have a
pretty-print filter,
anyway.
Most of all I don't mind usi

OK. But you mean emacs is not seeing _ as operator, if I understand correctly.
GNU smalltalk supports _ as ope

I'm using the underscore (_) as assignment operator;
As far as I can see, both Squeak and GNU smalltalk accept and support "_" as
assignment;

Also note that I set the remote address on the Datagram object.
I am not sure whether it matters, but I see in the code that you posted that
you set the remote address on the DatagramSocket.

Gary,
Here's a tcpdump in my case of the UDP test on port 13 between two different
systems
(192.168.0.1 and 192.168.0.2) :
# tcpdump -i net1 -nn -n -A port 13
dropped privs to nobody
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on net1, link-type EN10MB
Gary,
I cannot tell whether GNU smalltalk is stable or not,
only whether the simple datagram daytime test works for me ...
Also it may be that GNU smalltalk has different strengths than socket
programming,
the fact that they have on the roadmap for GNU smalltalk 3.3 a 'complete
rewrite'

Hi David and everybody,
I just sent my first UDP packet with Smalltalk Sockets. It's likely just me
but there might be some instability in gst. Somehow my Datagram Socket got
wiped out. I'm going to run tests and publish my findings here.

I suspect Cuis is also using the Unicode characters. I don't know.
But the idea of GNU Smalltalk is totally different, it seems GNU Smalltalk,
is about emacs, UNIX integration, command line etc. while Cuis is much more
graphically oriented (I think).

Note that the VIC-20 and C-64 and older Commodore machines indeed displayed it
as back-arrow:
https://en.wikipedia.org/wiki/PETSCII
PETSCII has only uppercase letters in its powerup state, an up-arrow ( ↑ )

I have a few (noob) questions about the UDP example Smalltalk program. More

Good morning David,
I'm not familiar with 'daytime' but will come up to speed on it and get it
and your use cases running and report my findings for everybody to see.
Hopefully netTest.c explains what I'm trying to do with Smalltalk. It's
very short and simple.

Hi,
I'm using a simple TCP/IP and UDP service called 'daytime' here.
This is a very old service, that is useful for small tests.
Traditionally this is a "inetd" service.
On my system, it is available as an inetd service.
Note that some Linux distributions do not install that service by defau
