The official way to do this "forever" has been the EXTRACT macro (and resulting SVC). But certainly the direct reference to TCBTIO has been in common use also roughly forever. But I see now that the EXTRACT macro has a newish (z/OS 1.1) note warning that you might have to use GETDSAB. Who'd a thunk it...
