Re: strange do loop problem

Hi Ozan,

I don't know if this was resolved, but I tried to reproduce this
myself without much luck.

Can you give us more information about what you are doing inside the
loop, and what the full dimensions of "data" are? If you can give us
the script and data so we can run it, that would be even better.

Thanks,
