Hi,

I have program in which I need to update VSAM file with field called pair, by reading it sequentially. But in VSAM file records are stored key ascending order. So when I update VSAM file, it is storing records in ascending order.
when I want to update new record, with 'pair', it takes whichever last stored value and update new one. So i am getting duplicate values in this field. Please let me know how can I update VSAM file without duplicating value

Thanks,
Jyoti
