Each Ptr assignment below yields the following error message:
-- 9. Ptr : a.X_Ptr := Object'Access;
-- >>> non-local pointer cannot point to local object
In the past, the only way that I seem to be able to fix the problem is to
put the pointer and assignment in global space (either in file global or in
a package spec). I've looked at Ada as a Second Language (Cohen) and, with
less diligence, at the Ada LRM but can't figure what I'm doing wrong. What
am I doing wrong?
