Hi,
I have the record-layou like this

01 Author
02 book
05 page pic 9(2)
05 para pic 9(1)
02 index x(3)

here "02 book" is the primary key.I have open the file in I-O mode and read the file dynamically using the primary key and rewrite the primary key .Ofcourse the primary key will be left unique.

Is this possible..Please help me......

As I recall, you read the rec, make sure you can get at the data, delete it, move the new key in and write it.

One other thing. I read something on another site that reminded me: it's safer to write the new rec BEFORE you delete the old one.
