You Can do it through JCL sort. Just add a seq number at the
last position of each record and sort it in descending order
of that seq number.
Here is the exacet code.
SORT FIELSD=COPY
OUTREC=(1,80,SEQNUM,4,ZD)
If your ps file is 80 byte long then this sort card a 4
digit seq num at 81 postion.
Now Sort the file on this seq num in descending
SORT FIELSD=(81,4,ZD,D)

I have File 1 occurs 5 times with Employee-ID,Employee-Name,Employee-Dept (EEE and MECH). I have File 2 occurs 10 times with Employee-ID,Employee-Name,Employee-Dept (EEE,CIVIL,CHEMICAL and MECH).
