Hi,
I have a file that I need to remove duplicates from. When the duplicates are removed, I need an output file that is unsorted - that is, it hasn't changed the order of the original file - that I'm getting the original file minus the duplicates.
Is this possible? Any ideas would be great!

use two sorts.
SORT 1:
SORT 1:
- add 6 char to length of output file
- put seqno in new 6 char
- SORT file based on keys that will identify dups
- use drop dups
- SORT key is seqno added by first sort
- use original record length (input to SORT 1) as length of OUTPUT, thus truncating the seqno added by SORT 1.
