VOLUME parameter for nonspecific volume requests

A nonspecific volume request can appear on a DD statement for a new data set; the data set is assigned to any volume or volumes. The nonspecific request is made through a VOLUME parameter that does not contain a SER or REF subparameter. The parameter can contain the following subparameters:

   VOLUME=(PRIVATE,RETAIN,,volume-count)

Note: The use of PRIVATE on nonspecific requests eligible to permanently resident DASD devices is not recommended. Operator intervention is required to allow the system to allocate such a request to a private volume.
