Subject: Question on Ada 9X vs Ada 83.
Message-ID: <CDrDrJ.4px@News.MR.Net>
List-Id: <comp.lang.ada>

I have a question about a compability issue and wonder if anyone on the
net
knows the answer or knows whom I could direct my question.

The issue is "Derived type inherits all operations of Parent".

An example is

  package P is
    type Some_Array is array (1 .. 10) of Integer;
    function "&" (Left, Right: Some_Array) return Some_Array;
    type New_Array is new Some_Array;
  end P;

I understand that in Ada 9X, New_Array inherits "&" from Some_Array and
that does not happen in Ada 83.

The my questions are:
  1 - Would this happen if these declarations were in a procedure body?
  2 - If the function declaration was moved after the type declaration
for
      New_Array would New_Array still inherit the "&" function from 
      Some_Array?

I have tried to figure this out by reading the Ada 9X RM but it was not
very clear to me.
