Hi,

I have this snippet of code (from members here) which defines a generic
type:

    generic
    type T is private;
        package P is
    type Node;
    type Node_Ptr is access Node;
        type Node is record
            Data     : T;
            Prev_Rec : access Node; -- points to the next record or
null if none exists.
            Next_Rec : access Node; -- points to the previous record or
null if none exists.
        end record;
    end P;

Now my compiler (gnat) complains that Node, and Node_Ptr are not seen
by the rest of the application. Is this because they are scoped within
package P?

If so, how do I 'import' the package? Right now I just stuck this at
the start of my main procedure:


procedure my_project is

    generic
    type T is private;
        package P is
    type Node;
    type Node_Ptr is access Node;
        type Node is record
            Data     : T;
            Prev_Rec : access Node; -- points to the next record or
null if none exists.
            Next_Rec : access Node; -- points to the previous record or
null if none exists.
        end record;
    end P;


    type PERSON_REC;
    type PERSON_REC_POINT is access PERSON_REC;
    type PERSON_REC is
        record
            m_strName    : UNBOUNDED_STRING;
            m_strPhone   : UNBOUNDED_STRING;
            m_strAddress : UNBOUNDED_STRING;
        end record;

so I thought it would have been visible by the rest of the application.


Thanks,
Mark
