RE: Update PF from Input Subfile

[KASHYAP VASWANI <kashyapv@xxxxxxxxxxxxx>]

First of all delete the record by chaining it after READC  after that you can 
directly write the changed records new value to the PF.
You will have to use multiple occurance data strucuture and in one occurance 
you delete the record and in the other you write new record . The description 
of data structure should be of that of PF. Write to me if you still have any 
problem.
