Hi Peter,
thank you very much for your help: __ code worked just fine!
I've also noticed the same result can be obtained by
declaring myData as const .
Both behaviours seems to be undocumented, or maybe
I'm just missing the right doc.
Accessing thru a pointer like tou did in your
example is not working though...
