This editor uses the Scroll Lock key to enable/disable the mode where
it keeps the cursor on the same line, and scrolls the file accordingly
as I move around.

Not very nicely.  It doesn't associate the command with its output,
or let you edit and re-execute old commands by moving through the
captured output.  But, no other editor apart from the one I use
does this either.  It is one of the nicest features of this editor
IMO.  OTH, EMACS's way of doing it would be OK most of the time.

That doesn't surprise me - I've used Borland's IDE too, remember :-)

Well, by selling TurboVision, Borland aren't necessarily saying that
they want you to write a program that uses exactly the same key
combinations and provides the same functionality as one of theirs!
But I'm sure they have more important things to worry about.

BTW, how are you able to distribute the source to a "port of Turbo
Vision"?  I thought Turbo Vision was a commercial product...?

Yes I have had a "quick play" with it.  Thanks for that note.

Okay thanks.

True, but I'd still need something for real-mode programs, functions and
interrupt handlers (for dual-mode interrupt handling).  But, you're
probably right.

I've investigated this and found that info works properly if I remove
my DJGPP environment variable.  In this case, 'info djasm' gives:

  info.exe: dir: No such file or directory (ENOENT)

I then put the DJGPP environment variable back, and tried commenting out
the INFOPATH line under [info] in djasm.env, and info worked properly
then too.  So I tried different settings for the INFOPATH line, for
example INFOPATH=C:/S/DJGPP/INFO, which is a valid directory, but nothing
seemed to work - info would always say 'bad command or file name' and
hang, requiring a reboot.

So it seems that if there is any INFOPATH setting in the [info] section
of djgpp.env, info hangs if the subject on the command line is unknown.

The original INFOPATH line was:

  INFOPATH=%/>;INFOPATH%%DJDIR%/info;%DJDIR%/gnu/emacs/info

Suggestions anyone?

Thanks again for your help.
