Perhaps you mean something like:
create or replace procedure my_proc
(p_my_parameter in varchar2 default null)
as
begin
   if p_my_parameter is not null
   then
      some_code;
  else
      some_other_code;
   end if;
end my proc;(but it's a bit 'funky' way of reasoning ;-) , I would take a different kind of logic... )
One other possible reason: you want to add the parameter to an existing proc, but keep dependent objects independent from the new parameter so you don't need to adjust them?
