Hi

I have an input file which has some records. It has a header and trailer. I would like to split the file based on two consecutive characters present in the detail records. The characters can be either 'AB' or 'AC'. The two files hence generated should have header copied from the original file. After splitting the trailer has to be updated to the new files with the new count. The trailer also has some text at the beginning and at the end of the trailer record the count has to be updated( count being of 8 character length). Kindly help

Thanks Suraj

Your description is too vague.

Please show an example of the records in your input file (relevant fields only) and what you expect for output. Explain the "rules" for getting from input to output. Give the starting position, length and format of each relevant field. Give the RECFM and LRECL of the input file.

Tell or show us what identifies the header and trailer.

Also, run this job and show the //SYSOUT messages you receive, so I can see what level you're at:

Code:

//S1    EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//SORTIN DD *
RECORD
//SORTOUT DD DUMMY
//SYSIN    DD    *
    OPTION COPY

Suraj.Nair,

Assuming your input is FB recfm and LRECL =80, the following DFSORT JCL will give you the desired results

Code:

//STEP0100 EXEC PGM=SORT                                     
//SYSOUT   DD SYSOUT=*

0011222333344445555AB E 145190273033344                       
0011139567890123456AC E 145190273033344                       
0011222333244445555AC E 145190273033344

  IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),

  IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),               
  IFTHEN=(WHEN=(1,3,CH,EQ,C'999'),                           
  OVERLAY=(20:81,8,ZD,SUB,+2,M11,LENGTH=8))

Alternatively, you can do it with the new IFTRAIL function of DFSORT like this:

Code:

//S1 EXEC PGM=SORT                                         
//SYSOUT DD SYSOUT=*                                       
//SORTIN DD *                                             
000 20110606165432                                         
0011134567860123456AB E 145190273033344                   
0011222333344445555AB E 145190273033344                   
0011139567890123456AC E 145190273033344                   
0011222333244445555AC E 145190273033344                   
999999999999999999900000004                               
//OUT1 DD SYSOUT=*                                         
//OUT2 DD SYSOUT=*                                         
//SYSIN DD *                                               
  OPTION COPY                                             
  OUTFIL FNAMES=OUT1,INCLUDE=(20,2,CH,EQ,C'AB'),           
    IFTRAIL=(HD=YES,TRLID=(1,3,CH,EQ,C'999'),             
      TRLUPD=(20:COUNT=(M11,LENGTH=8)))                   
  OUTFIL FNAMES=OUT2,INCLUDE=(20,2,CH,EQ,C'AC'),           
    IFTRAIL=(HD=YES,TRLID=(1,3,CH,EQ,C'999'),             
      TRLUPD=(20:COUNT=(M11,LENGTH=8)))

Hi

A small update to the above question.

Can we update the output files header with the type of accounts that are present, meaning, if the type is AB it should be present in the 19 position of the header.

Thanks in advance
Suraj

You can replace my DFSORT control statements with the following to make that change:

Code:

  OPTION COPY                                                         
  OUTFIL FNAMES=OUT1,INCLUDE=(1,3,CH,EQ,C'000',OR,20,2,CH,EQ,C'AB'), 
    IFTHEN=(WHEN=(1,3,CH,EQ,C'000'),OVERLAY=(19:C'AB')),             
    IFTRAIL=(TRLID=(1,3,CH,EQ,C'999'),                               
      TRLUPD=(20:COUNT-1=(M11,LENGTH=8)))                             
  OUTFIL FNAMES=OUT2,INCLUDE=(1,3,CH,EQ,C'000',OR,20,2,CH,EQ,C'AC'), 
    IFTHEN=(WHEN=(1,3,CH,EQ,C'000'),OVERLAY=(19:C'AC')),             
    IFTRAIL=(TRLID=(1,3,CH,EQ,C'999'),                               
      TRLUPD=(20:COUNT-1=(M11,LENGTH=8)))

Change Count-1 to Count+1 to add the count of header and trailer.

What do you mean it doesn't work? I ran this job

Code:

//STEP0400 EXEC PGM=SORT                                               
//SYSOUT   DD SYSOUT=*

    OPTION COPY                                                       
    OUTFIL FNAMES=OUT1,INCLUDE=(1,3,CH,EQ,C'000',OR,20,2,CH,EQ,C'AB'),
      IFTHEN=(WHEN=(1,3,CH,EQ,C'000'),OVERLAY=(19:C'AB')),             
      IFTRAIL=(TRLID=(1,3,CH,EQ,C'999'),                               
        TRLUPD=(20:COUNT+1=(M11,LENGTH=8)))                           
    OUTFIL FNAMES=OUT2,INCLUDE=(1,3,CH,EQ,C'000',OR,20,2,CH,EQ,C'AC'),

      IFTRAIL=(TRLID=(1,3,CH,EQ,C'999'),                               
        TRLUPD=(20:COUNT+1=(M11,LENGTH=8)))                           
//*


and I got
Code:

000 20110606165432AB                     
0011134567860123456AB E 145190273033344   
0011222333344445555AB E 145190273033344   
999999999999999999900000004               


The count is 4 records . You need to show me what you did.

Hi SKolusu,

You are right. I hadn't changed the TRLUPD for the first output so didnt get the updated count. Sorry for the inconvenience.


Thanks Suraj
