Hi group,

I am having 256 generation of GDG. Some of them contains only single record like
"HEADER"

and some contains records like

01 dsfds sdf 1254
02 sdf df 4512
HEADER

I want find out which generation contains only HEADER and which generation contains some other records along with HEADER.
I want to do this with the help of JCL.

Please help me.

Seems like you need to:

1. Create a list of all datasets in the generation data group.

2. For each dataset, allocate and open.

3. Read the contents and verify if it only has 1 record. If so, write the name of that dataset to a report.

4. Close the dataset, free the dataset. then repeat steps 2-4 until end of the list is reached.

If So, what d u want to do with the GDG versions..
