The StrCopy is copying 'Name' from the Data Record Structure to
somewhere else. Isn't that a 'read' from the Data Record Structure.
Certainly a 'read' is done from this area, else the Array could not
be filled. Data is 'read' from that area and the data is placed in
the array.

I have checked and there are no data records less than 3. The
smallest record is 38 bytes. And I have _no_ errors on the actual
device. Only POSE detects the error.
