Hi Norman,

As I said to Petr, READ-IO does *NOT* overwrite your buffer. If
you have data in it, it will append to it. So you either have to
skip the initial data when writing (but then you could end up
filling your buffer!) or clear it each time. (Notice that CLEAR is
O(1) so this does not add any performance problems.)
Regards,
Gabriele.
