Hi, Paul.

When I start Octave like this:
octave --interactive --path D:\\Octave\\OctaveBin\\share\\octave\\2.1.64\\m --exec-path D:\\Octave\\OctaveBin\\libexec\\octave

Then finds the oct and m-files in these folders. But it doesn't search recursively, how can I accomplish this?
That would be nice, so I don't have to copy ALL m-files into one directory.

I've recently found a readline for Win32. I will check this package shortly. ;)


Ole J.

By the way, here is a benchmark test of Octave-2.1.64 compiled with MinGW (gcc-3.2.3) on Windows XP.
This Octave works natively on Windows.

Are these timings good enough?
