That's what I imagined ;-)

I assume, that this will not helo much when converting from Numeric?
(sorry, I don't use Python myself). Thanks anyway.

I cannot assess the complexity of the code regarding Numeric/numpy, as I
don't use Python myself. I will forward these informations to the user
in question and hopefully he can manage to convert his files. I'm
afraid that will be a lot of files (he is using Numeric since many, many
years and never updated to newer packages)

We have that. It's the installation I want to get rid of...:-)
Thanks a lot
