Hi Claudio,
You need to flush the "stdout" buffer, which is sent to
the pager. Normally, you will only see the output when the
pager has a screen-full. If you flush it, the current
contents are displayed immediately.

For instance, try

  octave:1> for i=1:10
  >   i

  > endfor

I think you will find that this does what you want.

Best wishes,
Ted.
