"A combination of checked and unchecked convertions. First an unchecked
convertion to an access compatible modular type." (Martin)

>     X: Acc_To_Subp;
>     type Modular_32 is mod 2**32;
>     function Cast is new Unchecked_Conversion(Acc_To_Subp, Modular_32);
>     V: constant Vertex := (Tip => 0, Cue => Modular_64(Cast(X)));
(Bob)

This is a great idea. Bob's example made me understand Martin's 
suggestion. I think I'll do this. Thanks a lot.

I'll check. Thanks.
