DYNAM specifies that the volume to be processed is to be dynamically allocated. The volume must be mounted and online. You cannot specify a nonspecific volume serial number using an asterisk (*).

Using the DYNAM keyword instead of DD statements to allocate DASD volumes does not appreciably increase run time and permits easier coding of JCL and command input.

volser: Specifies the volume serial number of a DASD volume to be processed.
unit: Specifies the device type of a DASD volume to be processed. This parameter is optional.
