Answer 1

Ok, example using procedures, functions, IN and OUT parameters and variables.
Surely this should give you the answer.
SQL> create procedure B (v_val IN OUT NUMBER) is
  2  begin
  3    v_val := v_val * 10;
  4  end;
  5  /
Procedure created.
SQL> create function C (v_val IN NUMBER) RETURN NUMBER is
  2  begin
  3    RETURN v_val * 10;
  4  end;
  5  /
Function created.
