I do it this way, and I have to change Doubly_Linked_List(Info_Record) to
Indefinite_DoublY_Linked(Info_Record) cause of error:"unconstrained subtype in component declaration". Am I right? Or may be it's any way to use Doubly_Linked_List? And,BTW, I'm afraid of using Indefinite List cause I think,that it can request much more memory, than Doubly_C_L,isn't it?
