Exception handling has been available in PL/I from 1966, and has been routinely used in commercial and scientific programs, as well as, of course, real-time systems. and that >PL/I has no special advantage over Ada in this regard. Thank you. ---The PL/I exception and recovery capabilities are, in general, superior to those of Ada.
