Why won't this work
package MyList is new gen_linked_list( Integer, "=" );
type arggh is record
ID : Integer;
IntList : MyList.List;
end record;
when i compile i get. completion of nonlimited type cannot be limited.
is there a way to do this?

I'm assuming type List must be limited private which means that any type
that uses type List as a component must also be limited private.
type arggh is limited private;
private
type arggh is ...
end;

I understand that your Gen_Linked_List generic package declares the
generic type Gen_Linked_List.List formal parameter as being limited
private. In that case, you can't use it as a record component type
(assignment issues). The only workaround is to use an access to this
type. Like this:
type List_Access_Type is access MyList.List;
type Hggra is
record
Id : Integer;
Int_List_Access : List_Access_Type;
end record;
Of course, you'll have a manage your self allocations and deallocations
of objects of type List_Access_Type.
Jerome.
