Hi,
I need to do the following using sort(SYNCSORT) .I am having a flat file of length 80 and the data is like below.

HR08/20/2004
061
081
062
082
071
TR00090000290000000
HR08/19/2004
061
081
062
082
071
091
TR00090000290000000

I need to sort the detail records on the ascending order basis so that they will be in sorted order.

I need the output like below.

HR08/20/2004
061
062
071
081
082
TR00090000290000000
HR08/19/2004
061
062
071
081
082
091
TR00090000290000000

Now when there is only one header and one trailer I am able to sort the data.I found a similar post here but it has been dealt with only one header and trailer.How I can do this one if more than 1 header and triler were there in the input file.I am not sure how many headers and trailers will come on each day.Actually this is needed for our production support.

Thanks in advance..

Bprassana,

I can't think of a way to sort the records in between multiple headers and trailers with the available traditional features of sort.

So I used easytrieve to populate the number at the end of each record , so that all the detail records can be identified as a group.

Code:

//STEP0100 EXEC PGM=EZTPA00                   
//STEPLIB  DD DSN=EASYTREV.LOADLIB, 
//            DISP=SHR                         
//SYSPRINT DD SYSOUT=*                         
//SYSSNAP  DD SYSOUT=*                         
//INFILE   DD *                               
HR08/20/2004                                   
061                                           
081                                           
062                                           
082                                           
071                                           
TR00090000290000000                           
HR08/19/2004                                   
061                                           
081                                           
062                                           
082                                           
071                                           
091                                           
TR00090000290000000         
//OUTFILE  DD DSN=USERID.TEMP.FILE,           
//            DISP=(NEW,CATLG,DELETE),         
//            UNIT=SYSDA,

       OUT-REC            01 80  A             
       O-SEQ              81 08  N 0           
                                               
  W-SEQNUM       W 08 N 0                       

  JOB INPUT INFILE

           WHEN 'HR'                           
                W-SEQNUM     = W-SEQNUM + 1     
           WHEN 'TR'                           
                W-SEQNUM     = W-SEQNUM + 1     
      END-CASE                                 

      O-SEQ                  = W-SEQNUM         
      PUT OUTFILE                               
//*
//STEP0200 EXEC PGM=SORT           
//SYSOUT   DD SYSOUT=*             
//SORTIN   DD DSN=USERID.TEMP.FILE,
//            DISP=SHR   
//SORTOUT DD DSN=YOUR OUTPUT SORTED FILE,           
//            DISP=(NEW,CATLG,DELETE),         
//            UNIT=SYSDA,                       
//            SPACE=(CYL,(X,Y),RLSE)
//SYSIN    DD *
  SORT FIELDS=(81,8,CH,A,     $ SORT ON SEQNUM
               01,3,CH,A)     $ SORT ON KEY     
  OUTREC FIELDS=(01,80)       $ STRIP THE SEQNUM
//*               


Hope this helps...

Cheers

Frank,

May I have your opinion about this : do you have an idea if it is feasible with dfsort ?
Yes or no is enough for me. If it is no, I could test something on monday. Smile

Alain,

It's irrelevent since bprasanna asked for a Syncsort solution.

Frank,

I'm agree.
During a search for a potential Dfsort solution and for my personal curiosity, I found an old thread (1 month ago) from an other forum with the a similar need. If I find something I will post it down there.
