DD VOLUME Parameter
DD VOLUME Parameter
The VOLUME parameter is used to specify the name of the DASD (Direct Access Storage Device) volume on which a dataset is stored or is to be stored.
The volume can be private and is an optional parameter.
Syntax -
{VOL}=([PRIVATE][,RETAIN][,volume-sequence-number][,volume-count]
{VOL}=[SER=(serial-number[,serial-number]...)]
{VOL}=[REF=*[.stepname][.procstepname].ddname| PRIVATE | Requests a private volume. |
| volume-sequence-number | Specifies the unique number to identify the volume. The volume sequence number is from 1 through 255. The system assigns the first available volume with the requested space if it is not coded. |
| volume-count | Specifies the maximum number of volumes. A volume count is a decimal number from 1 through 255. The total volume count for all DD statements in one job step cannot exceed 4095. |
| SER=(serial-number[,serial-number]...) | Specifies the volume serial number. A volume serial number is 1 through 6 characters. Users can code 255 volume serial numbers on a DD statement. |
| *.ddname | Specifies the system should get the volume from the previous ddname from previous steps. |
| *.stepname.ddname | Specifies the system should get the volume from the previous ddname from previous stepname. |
| *.stepname.procstepname.ddname | Specifies the system should get the volume from the previous ddname from previous stepname of the procstepname. |
Examples -
