not implemented, they are causing a link time error on z/OS. Hence, is there a plan to implement them? Or is there a way to cause compiler time errors if those functions are used? If not, should we leave it as is or provide a definition that asserts (to be
more user friendly)?. <o:p></o:p></span></p>
