Like this ...
private
Protected_Value : Integer := 0
with Volatile,
Part_Of => State;
end PO;
but I still get the problem with Impl ... so I put its spec in po.ads
similarly ... State still needs refinement, but it can't be done ...
1. package body PO
2. with Refined_State => (State => (Protected_Value,
|
>>> non-external state "State" cannot contain external constituents in refinement
3. Impl))
4. is
