Bruce, This conflicts with BLKSIZE=0 being used for SDB. SDB does not work unless DSORG can be established. BLKSIZE=0 is a null - SDB requires DSORG and no BLKSIZE. Additional DCB depends on the DSORG.
Most sites have a default DATACLAS that will allocate with DSORG=PS if nothing else can be determined. This allows SDB to work, and also ensures SMS datasets have an EOF at allocation.
