This is false information. In many instances, outlined clearly
in the RM, the questioner is right, an IN OUT parameter and
an OUT parameter are identical.

Yes, from a conceptual documentation point of view, if you
use OUT, then you should not read the parameter, but the RM
is quite clear that this in many cases this is just a
documentation convention and nothing more.

This is true for all by-reference types, and in particular, for
all tagged types OUT is exactly the same as IN OUT
semantically.
