I am not sure whether "more off" does the trick, the output would still
be buffered. Please try "page_output_immediately (1)"

>From the help for page_output_immediately:
"Query or set the internal variable that controls whether Octave
sends output to the pager as soon as it is available.  Otherwise,
Octave buffers its output and waits until just before the prompt
is printed to flush it to the pager."
