Notes for OUTDDNAME and OUTDYNAM Keywords

DFSMSdss now distinguishes between non-SMS and SMS volumes specified in the OUTDDNAME or OUTDYNAM keywords. For non-SMS allocations, only the volumes that are non-SMS are considered for allocation. Similarly, only SMS volumes are considered for SMS allocations.
The above distinction is also used when determining the volume count for a multivolume allocation. Where volume count is determined from the number of specified volumes, only those volumes eligible for the type of allocation being done are counted. If there are no volumes that match the type of allocation (SMS volumes for SMS allocation, or non-SMS volumes for non-SMS allocation), processing proceeds with a null volume list.
