Hi Mike,
My approach  was to run the octave jobs  from a shell script that I started
in the background with the at daemon.
I use bash under linux, so it might be  a little different , but in .bashrc I
had

alias run000='at -f /home/jcw/model0/atrun000.sh -m now'

Then that script  would invoke octave.

octave -q  run000.m

Actually the shell script wrote the octave scripts from a template, plugging
in the correct values with sed.  The octave runs themselves would each write
a line into a .csv  file suitable for importing into a database as well as
properly labeled files suitable for plotting.  One shell script can run a lot
octave scripts.  You can plan a whole day's work for your computer while you
go do something else.

Hope that helps,
Jonathan
