If it is just a matter of running the .m file once a second, you can
do it within octave:

while (some condition)
  sleep(1)
  mfile
endwhile

Otherwise, many programming languages, even on windows, have some
form of `pipe open'. The parent program creates a file identifier,
but instead of opening a file for writing, it starts up a child
program and sends data to its standard input. The parent could write
instructions to the child every second.

This is also described in the Octave manual, but with Octave as
parent; search for popen.

I know this to work under Windows with Tcl as parent and Octave as
child. I have never tried anything of the kind with Delphi or VB as
parent, though.
