True, but I think the original poster wanted Write to be accessible to
*this* package (in the body), but not accessible to outside packages.
The above doesn't do that.

Another post showed how to wrap the call to the protected Read in a
normal procedure, and put the whole protected type in the package body.
That works, but if the exported thing was an entry, then it wouldn't --
outsiders wouldn't be able to do entry-ish things to it, such as requeue
to it, do a timed call to it, &c.
