123678 20385907 9797 666
17978975 87468976 968978 98798

I am trying to have out put which actually look for the third column value of 9797 and then it insert line there after with first, second column value exactly as the previous line and replace the third by value 5000 and the next one 700
so finally the o/p file will look like
Code:
2356798 7689867 999 000
123678 20385907 9797 666
123678 20385907 5000 700
17978975 87468976 968978 98798

and so on....

Any help on this is much appreciated.
