Copy unknown number of GDS generations

Hi,
I know we can use IEBGENER to copy by giving corresponding file in SYSUT1 & getting the desired output file thru SYSUT2. How can I copy generations from GDG to another without giving the generations of the file? My job runs on adhoc basis & can create a max of 30 files a month. So end of month I want to copy all the generations created to another GDG. Since number of generations is random, I want some generic logic to copy the GDG files.

will the following work? AF123.ABCD & AF123.WXYZ being GDG BASE

//STEP110 EXEC PGM=IEBGENER
//SYSUT1 DD DSN=AF123.ABCD,DISP=SHR
//SYSUT2 DD DSN=AF123.WXYZ,DISP=SHR
//SYSIN DD DUMMY
//SYSPRINT DD SYSOUT=*

Appreciate your quick response.

Thanks,
Ranjini

DO NOT start a new topic on the back end of an existing one.

Your post is not very clear. Do you want to copy generation to generation, or to merge all of them into just one new generation of the other GDS.

If you want to copy generation to generation take a look at DFdss (PGM=ADRDSSU)

Ranjini,
I'm still not certain whether you want to copy:

30 GDG files to 30 new GDG files with same generation numbers, or
30 GDG files to 1 new GDG(+1) file??

Sounds like you have multiple input generations that can vary in number each month, and you want to combine them into one single generation of another GDG? If yes, all you have to do is specify the GDG base name as the input file and all generations will be read in regardless of the number. You can do that with an IEBGENER or SORT.
