I see what you mean.  It might be nice if such things could be controlled
within a script or function, but they wouldn't alter the global octave
environment (and interfere with other scripts/functions).  They would then
work like unix shell variables.  Maybe that doesn't make sense for
functions but it might be good for scripts.

I'll vote for the most sensible.  Once they are set to known defaults, the
script could then set them to whatever was needed.  It would be handy for
developing code to know that it will work the same for everyone.

Thanks *very* much for your quick replies!
