Hi,

I need to sort a file & create an output.

The input file is in this format
Code:

9901xxxx
    1111
    2222
    3333
9902yyyy
9902zzzz

As you can see i have 2 trailers with each having a count value which sums up to total number of detail records.

In my final output i want only one trailer record with a sum of counts value.

Apart from this i have some sort conditions for detail records as well.

Is it possible to achieve all these functionality in a single sort step?

sameermn,

Couple of questions before I post the solution.

1. What is the LRECL and RECFM ?

2. How do you identify the header and Trailer records?

3. In between the 2 headers which one do you want in the output

Hi Kolusu,

Thx for your response.

1. LRECL = 491 and RECFM = VB

2. Header = 1st 4 bytes 9901, Detail = 1st 4 bytes spaces,
Trailer = 1st 4 bytes 9902

3. Of the 2 Trailers, we can have any one among them as the only value here is the count (from 5th byte 10 positions) which needs to be summed up in to one single record.

Also as i mentioned earlier i need to sort detals records based on criteria

SORT FIELDS=(260,03,CH,A, 272,05,CH,A, 277,08,CH,A, 285,13,CH,A,
263,02,CH,A, 302,09,CH,A)

Regards,

Hi Kolusu,

Made a small mistake.

Header 1st 4 bytes = 9900
Detail 1st 4 bytes = 9901
Trailer 1st 4 Bytes = 9902

Regards

sameermn,

The following JCL will give you the desired results. I assumed that you want the header record also to be counted as a part of the total records.

Code:

//STEP0100 EXEC PGM=SORT             
//SYSOUT   DD SYSOUT=*               
//SORTIN   DD DSN=YOUR INPUT FILE,
//            DISP=SHR
//SORTOUT  DD DSN=YOUR OUTPUT FILE,
//            DISP=(NEW,CATLG,DELETE),
//            UNIT=SYSDA,
//            SPACE=(CYL,(X,Y),RLSE)
//SYSIN    DD *
  OMIT COND=(5,4,CH,EQ,C'9902')       
  SORT FIELDS=(005,04,CH,A,           
               260,03,CH,A,           
               272,05,CH,A,           
               277,08,CH,A,           
               285,13,CH,A,           
               263,02,CH,A,           
               302,09,CH,A)           
 OUTFIL TRAILER1=(C'9902',COUNT)     
/*


If you don't want the header record to be a part of the total count then, then use the following control cards.

Code:

//SYSIN    DD *
  OMIT COND=(5,4,CH,EQ,C'9902')                 
  SORT FIELDS=(005,04,CH,A,                     
               260,03,CH,A,                     
               272,05,CH,A,                     
               277,08,CH,A,                     
               285,13,CH,A,                     
               263,02,CH,A,                     
               302,09,CH,A)                     
  OUTREC FIELDS=(1,4,                           
                 5:5,4,CHANGE=(1,C'9900',C'0'),
                                NOMATCH=(C'1'),
                 5)                             
  OUTFIL OUTREC=(1,4,6),                       
  TRAILER1=(C'9902',TOT=(5,1,ZD,EDIT=(TTTTT))) 
/*


Hope this helps...

Cheers

Kolusu
