When u open th ePDS using option 3.4
you see the list of Members. In that you can check last changed and who did it. in this way anyone can check.

Try the following code in Sort

Quote:
INREC FIELDS=(1,80,SEQNUM,8,ZD) // assigns the SEQNUM to 81st col
SORT FIELDS=(81,8,ZD,D) // sort the seqnum in DESC order
OUTREC FIELDS=(1,80) // write the output excluding the SEQNUM.


Hope it helps you.

Regards
Rupesh
