Using Selected versions of GDG as input file

Hi,

I have a GDG with 10 versions. I would like to use only the last 5 versions of the GDG as an input file in my job. is it possible to use them without hard coding like the combination of GDG(0) to GDG(-4) ? I know I can use the GDG base as input if i want to use data in all the versions of the GDG. I want to use only the last 5 versions, because I know the data is present in only the last 5 versions. If I use the base GDG as input the job runs for hours as all the versions of GDG are read.

Thanks for your replies.

Anu Narayanan,

The way you describe GDG(-4) thru GDG(0) is the accepted way of doing this.

Hi Rohit,

yes you are right. If the Base GDG is xxxx.yyyy, then I would be using xxxx.yyyy(0)
xxxx.yyyy(-1)
xxxx.yyyy(-2)
xxxx.yyyy(-3)
xxxx.yyyy(-4) in the input files
Hope you are clear.

Thanks,
Anu Narayanan
