Will do.

There are a ton of functions I've never known about in
octave.

Is this a new version to download?

I have a great deal of difficulty navigating through the
manual. But will take a look.

Didn't know about that.

yeah, forgot to cc the group.

How?  I looked for java on my WinXP system and found two
empty folders in C:\WINDOWS\Java

Is java only used by octave?  Or will there be some benefit
from having java installed?

ARRRRG!
I once installed cygwin and instantly became confronted
with all kinds of problems that I could not sort out, so
had to remove it.  When I say 'could not sort out' I even
refer to the symptoms I got hit with.  Couldn't even
articulate them. So no way to fix them.  Easiest solution
was to remove cygwin.  

No doubt about it.  Got to get Linux up and running and get
out from under MS.
