I have file with below format
Code:

00 AAAAAA
01 123456
01 123457
01 123458
99 AAAAAA
00 BBBBBB
01 987654
01 987653
99 BBBBBB

The firts two bytes shows the record type
Code:

00 - Header
01 - Detail record
99 - Trailer

I want to update each subsequent set of header and trailer with same sequence number.
like as shown below
Code:

00 AAAAAA001
01 123456
01 123457
01 123458
99 AAAAAA001
00 BBBBBB002
01 987654
01 987653
99 BBBBBB002

Please let me know how can this be done through Dfsort.

psmadhusudhan,

You can use the following DFSORT control cards

Code:

//SYSIN    DD *                                                 
  OPTION COPY                                                   
  INREC IFTHEN=(WHEN=(1,2,CH,EQ,C'00'),OVERLAY=(10:SEQNUM,3,ZD)),
        IFTHEN=(WHEN=(1,2,CH,EQ,C'99'),OVERLAY=(10:SEQNUM,3,ZD))
//*
