Answer 1

In the example from the question nested procedure is only declared but never called. To run the nested procedure the call has to be present between BEGIN and END statements:

BEGIN

  SELECT Ship_name , Captain_Name
  INTO o_name, o_capitan
  from  Ship WHERE registry_country LIKE p_register || '%';

  showshipsDisp(o_cap => ?
               ,o_dis => ?);

END;

Question marks should be replaced by proper variables.
