The PHYSINDYNAM keyword specifies the input volume that is to be dynamically allocated to a physical copy or dump operation. A nonspecific volume serial number cannot be specified by using an asterisk (*). Only one volume may be specified for a FULL, TRACKS, or DATASET COPY. The device described by the volser must be the same type as the output device specified on the OUTDD or OUTDYNAM keyword.

PHYSINDYNAM may be abbreviated to PIDY.
