i am giving you pseudo code of same
suppose we have 5 records
rec-no 1-->10
rec-no 2-->1
rec-no 3-->25
rec-no 4-->35
rec-no 5-->20
read sequential file to get record count of file
close file
define an array whose size is equal to record count of file
open file
read file in loop
move current record of sequential file to last subscript of
array define above ( this can be taken care using perform
varying)
read the array starting from subscript 1 to record count
this will be similar to reading sequntial file in reverse
order.....
thanks,
Abhishek
