As I have said many times on help boards, a model / pattern DSCB is not required for ANY GDG being created. Go talk to your storage people and ask them to set up a dummy DATACLAS to be allocated to ALL GDG datasets being created, DASD, Tape, SMS, NONSMS.
Makes life so much easier. Your model DSCB may have a BLKSIZE of 233 which would be a performance pain.
