Hi Asokrani,

type 'QW RETAIN' in the command prompt and you will find a clear description about VOL parameter. Excuse me, if you already knew this and still wanted to know in detail.

Hello,

Whether your system has QW or not (many do not), you want to become familiar and comfortable with the documentation. At the top of the page is an "IBM Manuals" link to most of the every-day documentation for multiple releases of IBM software.

Here is the link to the page that has the answer to your question:
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/handheld/Connected/BOOKS/iea2b650/12.1.4?

What you are looking for is near the bottom. . .

Hi,
Quote:
VOL=(,RETAIN..
This requests that the volume not be demounted or rewound when the data set is closed - a public tape volume will be retained at the tape drive if it is demounted during the job. From manuals - JES3 systems will honor RETAIN only if the volume is actually used in a later job step.

Quote:
..25)

25 says, that this output can use at the most 25 volumes. {Vol count} is a decimal number in the range 1 through 255, inclusive - the total number of output volumes for a DD statement may not exceed 4,096 volumes, however.

Other "," (commas) are place holders for the optional sub-parameters in VOLume parameter.
