Yes.

Yes. Yes. I'm not clear on what you are trying to ask in your last question.
The Delphi (Object Pascal) Language Reference section of the help details
this in an early chapter - its a good read anyway.

procedure One;

var vOne : tType;

begin
end;

procedure Two;

Procedure TwoOne;

var vTwoOne : tType;

Function TwoTwo : tType;

begin
end;

var vTwoOne2 : tType;

begin
end;

begin
end;

One sees vOne, and Two but nothing inside Two. Two sees One, but nothing
inside it. It also sees TwoOne, but nothing inside it. TwoTwo sees TwoOne,
Two, and One. It also sees vTwoOne, but not vTwoOne2.
