My pds a.b.c contains only one member named a1.
I have to copy a1 to a2, a3,......a100 in the same pds so that my pds a.b.c should contain 100 members (a1,a2,a3,....a100) after this.
Using IEBCOPY or IEBUPDTE we can have only one input dataset and only one output dataset.
Please send me the code in this regard at the earliest.
