Thanks a lot. Now that I know what the differences between binary and ascii
tranfer mode are I'll be able to correct the files if they don't work
because I used the wrong method.
As for the newer version, I don't know which one to use. I've already
explained my problem/question a my previous mail.

Thanks again.
Fred
