Dear Eric,

thanks for your quick reply and sorry for taking so long to get back to
you.  I ended up going to Chile for a week the day after sending my
original email and had very little Internet access (and, actually, no
time even if I had had proper connectivity).  Back now!

Ah ha, this is a subtle one!  The output looks the same in either case,
as Nick D. also notes.  By changing the results generated to value and
not output and adding an expression at the end of my octave code to
generate the value required got things working.

The subtlety makes this a rather frustrating experience, however.  Is
there any way to convince babel to treat a string output as an org table
so that subsequent chaining works in this case as well?

Thanks again,
