Does splitting Inno Setup Pascal Script code to sub functions/sub-procedures impact performace?

Question

I'm creating all the pages directly on InitializedWizard section (they don't have order of creating for Example; Page2, Page5, Page1) like

procedure InitializeWizard;
var
  Text : TLabel;
Begin
  Page2 := CreateCustomPage(Page1.ID, '', '');
  Text := TLabel.Create(page2);
  Text.Left := ScaleX(0);
  Text.Top := ScaleY(35);
  Text.Caption := ''; 
  Text.Parent:= Page2.Surface;

  Page5 := CreateCustomPage(Page4.ID, '', '');
  Text := TLabel.Create(Page5);
  Text.Left := ScaleX(0);
  Text.Top := ScaleY(35);
  Text.Caption := ''; 
  Text.Parent := Page5.Surface;
End;

I there is a difference, if I create the pages on separated procedures, and then call them in InitializeWizard like this?

procedure CreatePage1;
var
  Text : TLabel;
begin
  Page2:= CreateCustomPage(Page1.ID, '', '');
  Text := TLabel.Create(Page2);
  Text.Left := ScaleX(0);
  Text.Top := ScaleY(35);
  Text.Caption := 'Tickets Printer'; 
  Text.Parent := Page2.Surface;
end;  

procedure InitializeWizard;
begin
  CreatePage1();
  CreatePage2();
  CreatePage3();
end;

Answer 1

There's no practical performance difference between:

procedure Master;
begin
  Statement1;
  Statement2;
end;

and

procedure Child1;
begin
  Statement1;
end;

procedure Child2;
begin
  Statement2;
end;

procedure Master;
begin
  Child1;
  Child2;
end;

If that's, what you ask.
