concatenate two gdgs into a new GDG

I have two GDG datasets (both will be the most recent generations), which I need to concatenate to produce a third GDG - how do I do produce this third file?

eg. ABCDEF.G0283V00
123456.G0283V00

I need the contents of both these files in a new generation, ABCDEF.G0284V00

thanks

Hello,

You might use IEBGENER or SORT.

For the input, concatenate your.dsn(0) and your.dsn(-1) and use your.dsn(+1) as the output dataset name. If you use this approach, you will not need to change the jcl for every run to use the specific version.

Option #1 if DCB parameters are same

You can use (0) to get current GDG version.
ABCDEF(0)
123456(0)

Option #2 if DCB parameters are different, then code below 2 steps in same job.
copy ABCDEF(0) to new GDG ABCDEF(+1) with DISP=(New,catlg,delete)
copy 123456(0) to same GDG ABCDEF(+1) with DISP=(MOD)

If the GDG are created in same job then you need to use (+1)
