Subject: break
Message-ID: <[e-mail]>

Does anybody know how break (i.e., ~C) works on the ST?
Is it something in TOS?  (I wouldn't think so since I don't
remember hearing about it, and I know some programs don't break.)
Is it done in each language?  For instance, does _main() in
Sozobon C scan stdin for ~C and _exit() if it sees it?
(I wouldn't think so since then everything would have to
worry about it.)

I'm asking because I'm toying with the idea of a vi-type
Korn shell based on RTX.  I like gu:lam but I don't like microEmacs,
and I miss multi-tasking and job control.  So, thinking about
device drivers, SIGSTOP, and the like, I really should understand ~C.
I suppose I could just have the cli slip in an isr to monitor
whatever tty-type input devices, and grap any ~Z that comes along,
but there'll probably be complications if I don't understand
what else is going on.

Or, does Dave Beckmyer's (sp?) shell have vi-like command line editing,
and job control?  I haven't seen it, and from what I heard it's a C shell,
but if it does have those other features I'd hate to re-invent the wheel.
I've seen the RTX docs and have the highest respect for RTX's design
(it reminds me of the kernel my OS Lab team did).

Yes, this would be an excellent way to spread documentation about the
ST. How about one example for each BIOS, XBIOS, and GEMDOS call? A few
complete AES/VDI-based programs? Examples that show how to read the
right mouse button, use the VBI queue, work with GDOS.

Any volunteers?

Ditto.

Yes, I am replying to myself.

Sincere apologies - I didn't realize that there is a facility for changing
the portion of the screen which is in view at the given time.
The / key on the numeric keypad lets you view the left edge, right edge,
or the center of the screen (cutting off both sides partially).

I stand corrected. It was a two little lines in the manual which i
must have missed the first few times around...

Subject: update on getting GNU Emacs to work
Message-ID: <[e-mail]>

I was finally able to dump GNU Emacs.  I fixed the problem of temacs
reporting "End of file during parsing" reading through the loadup.el file by
commenting out the reference to "load site-load file" and just including the
contents of the site-load file itself.  As far as I know, running 'dumpfix'
went OK and I now have a valid dumped emacs.

The question is now: when I run xemacs, it always says that it can't find
the termcap file.  There is a file in the distribution which claims there is
a sample termcap entry for the atari included, but I can't find the sample
anywhere.  Does anyone have a termcap for atari's vt52 emulation?  For now,
I'm going to get all vt52 entries out of the termcap file here, but a
specialized termcap for the atari is probably better.

Thanks to Ed Roeder for his help in getting me this far.

Access to the /atari/new directory has been changed to write-only for
anonymous ftp users. Probably so programs can be checked out before people
start using them, or maybe to stop people from using that directory for
their own purposes, I don't know.

This is a simple security precaution. By preventing anonymous users from
seeing the filenames in the directory, we reduce the chance that some malicious
screwball will replace a valid program by a virus-infested one (for example)
by uploading a new file with the identical name. There aren't too many good
solutions to managing an archive that's globally writable.

Hard to imagine someone deliberately sabotaging an archive site, but ya never
know. At any rate, with the new indexing efforts, files shouldn't stay in new
very long anyway.
