The INDYNAM keyword specifies the input volumes that are to be dynamically allocated and copied. The volume must be both mounted and online. You cannot specify a nonspecific volume serial number by using an asterisk (*). Only one volume is allowed for a FULL or tracks COPY. Data set copy operations allow multiple volumes. To ease JCL coding and command input without appreciably increasing run time, use the INDYNAM keyword instead of data definition statements to allocate DASD volumes.

volser

Specifies the volume serial number of a DASD volume that will be copied.

unit

Specifies the device type of a DASD volume that will be copied. This parameter is optional.
