Questions - Polimorphism/Dynamic Binding

[Eric Merritt <cyberlync@yahoo.com>]

Hello all,

I have basicaly two questions that I hope will be
fairly easy for you guys to answer.

1)

I started out in Java and C++ and recently found the
one true langauge (Ada95, lol). In any case, one thing
that I found very usefull in Java was the Interface. I
don't believe that Ada has this at all. I was
wondering if there is a way to impliment this type of
functionality in Ada (If required I can provide
examples). This also leads to my second question.

2)

If you have a tagged type and extend that type with a
new type. Then pass the new type to a procedure that
accepts its the new types parent, the original type.
Are procedures associated with the child type
(methods) that override it's parent types procedures
called in this instance, even though the procedure
that  this type is passed into is unaware of the new
child type and has not withed it's package?

I hope these questions have been somewhat understandable.
