Hmm.. good question. :)

I was under the impression that the second \5
bracketed the end of the "octave>" prompt, and that
the initial
\2 was NEVER closed (and hence all output is verbatim
by default). 

In fact, hacking this stuff into octave and bash was 
my test for this assumption. Hmm. It works but
something is very wrong.

Done.

I haven't looked into Maxima much yet. As I recall the
filesize was prohibitive when I looked into it awhile
back. I chose Yacas because it is written in a Lisp
dialect, but I see now that Maxima is written in
Common Lisp.. so Maxima does appear to be a better
choice.

I am sure there is a way to fork a different
executable, instead of less, as there is with texinfo.

That executable could process the long stream from
Octave any way that it desires in order to make it
TeXmacs friendly. A glorified 'cat' will do the job
nicely. 

Note that when communicating through a pipe, Octave
doesn't use less. 

The use of texinfo for help -i is a related problem,
though. 

If TeXmacs could read texinfo files, we'd be in
business :)

Why not just generate a simple table via Scheme? 

(block* (tformat (table (row (cell ...

?

This exact example is not vertically aligned, but it
is visually appealing and easy to read.

Well, I'm thinking about the future. Octave uses
gnuplot, and gnuplot can produce figs. At some point,
I'd like to enable Octave to feed fig drawings and
data plots directly into TeXmacs. 

Plus they are called _GNU_ Octave and _GNU_ TeXmacs.
If GNU's applications don't work together how can it
ever be taken seriously as an operating system?
