Can you give us the context in which you need this?
What do you mean by "base class"?
Technically the base class for everything is TObject and I am sure you do not mean that.
It also depends on how the method is declared and whether you are talking about
calling it from within a descendent or from another object or unit.

Use keyword inherited before the name of the method of the parent class you want to call. For example:

Code:
procedure TChild1.PrintText(const AText: string);
begin
  inherited PrintText(AText);
  ...
  ...
end;



Actually if the parent method have the same name and the same parameters with the one where the descendant would call it (like in the example above). You can get away with only inherited. Like this:

Code:
procedure TChild1.PrintText(const AText: string);
begin
  inherited;
  ...
  ...
end;
