where is the prompt: 0,1,2?

[Daniel Heiserer]

Hi,

where does the octave prompt come out?

I thought that it is on stdout (1).
But when I run octave like this, and then write some stuff like:
------------------------------------------------------
octave > tmp
a=rand(4)
24355
exit
cat tmp

ans = 24355
------------------------------------------------------
So the prompt neither appears on the terminal anymore
which is quite clear when it is on stdout(1), but
then it should be redirected into the file tmp.

So on which filedescriptor is the prompt?
Or does octave not output a prompt once it knows
eihter stdin/stdout are redirected somehow.
but can octave know that, and if how?
