Help with access types

[James Kerr]

Okay basically I have a Specification that has this in the private section

private

    type Node(Length: Integer);
    type Tree is access node;
    type Tree_Array is array (Integer range <>) of Tree;
    type Node(Length: Integer) is
        record
            Marker: Boolean;
            Symbols: Symbol_Array(1..Length);
            Subtrees: Tree_Array(1..Length);
        end record;

Okay what is the easiest way to access these record variables, (IE Marker,
Symbols, Length) from a program that is using this specification.

Basically in the body I have an Add procedure which adds nodes to the tree,
i want to be able to check the record variables from a test program I have
written,

any ideas

mail me at

cheers

Can you give a bit more of an idea of why there is an issue
here? There seems to be nothing special about these types that
would preclude using normal record and array component notation.

Well, other than that they're in the private part of the specification,
which limits (intentionally)
which parts of the program can access these variables.

Does the statement "program that is using this specification" mean something
other than the body of the
package (or a private child of this package)?
