The initial setting is in SYSTEM CONFIG, FEATURES DYNAMIC_IO. You can also disable the SET DYANAMIC_IO command there, too. You may still find that there is no room in the IOCDS because you didn't use the DYN option on IOCP, but that's not what's stopping you at this point. Alan Altmark z/VM Development IBM Endicott
