If you read the JCL Reference manual, you will find that you must catalog the new version using the fully qualified name SAMDIP.TEST.GDG.G0001V01 -- the old version will be uncatalogued automatically.

Hello,

Why do you believe you want/need to use "version"?

What kind of business requirement makes this necessary. Or - Is this just another solution looking for a requirement?

I only ask because i have see 10's or 100's of thousands of gdg datasets across several thousand applicaton environments and have not yet seen a need to use a version for one of these datasets. . .
Hope this helps,
d.sch.

Hello,

I expect that your "senior" has been misunderstood or does not themself understand what is needed. . .

I don know much about his pgm but as a beginner i will look forward to acquire knoweledge of such things as well
Why does knowledge of the program have anything to do with "generation" or "version"? What is to happen when the "next" file is created?

There needs to be a much better understanding of what is happening before something is just thrown in because of needint do to something".
Hope this helps,
