Hi,

I have two files as below.

File 1 Content

AAA BBB CCC
AAA EEE FFF
AAA GGG HHH
GGG HHH III

File 2 Content

XXX
YYY
ZZZ
WWW


I want my output file should be as below

AAA BBB CCC XXX
AAA BBB CCC YYY
AAA BBB CCC ZZZ
AAA BBB CCC WWW
AAA EEE FFF XXX
AAA EEE FFF YYY
AAA EEE FFF ZZZ

For each entry in file 1 should have entries for file2. Number of records in file 1 and file 2 always varies.

Is it possible to do?

Sasikumar,

Try this:
Code:
//STEP1 EXEC PGM=SORT                       
//SYSOUT  DD SYSOUT=*                       
//SORTOUT DD DISP=(NEW,PASS),DSN=&&TEMP1,...   
//SORTIN  DD *                               
AAA BBB CCC                                 
AAA EEE FFF                                 
AAA GGG HHH                                 
GGG HHH III                                 
//SYSIN   DD *                               
  SORT FIELDS=COPY                         
  OUTREC OVERLAY=(12:C' ')
//*********************************               
//STEP2 EXEC PGM=SORT                     
//SYSOUT  DD SYSOUT=*                       
//SORTOUT DD DISP=(NEW,PASS),DSN=&&TEMP2,...   
//SORTIN  DD *                             
XXX                                       
YYY                                       
ZZZ                                       
WWW                                       
//SYSIN   DD *                               
  SORT FIELDS=COPY                         
  OUTREC OVERLAY=(4:C' ')
//**********************************                 
//STEP3  EXEC PGM=SORT               
//SORTJNF1 DD DISP=SHR,DSN=&&TEMP1 
//SORTJNF2 DD DISP=SHR,DSN=&&TEMP2 
//SORTOUT  DD SYSOUT=*               
//SYSOUT   DD SYSOUT=*               
//SYSIN    DD *                       
  JOINKEYS FILES=F1,FIELDS=(12,1,A)
  JOINKEYS FILES=F2,FIELDS=(4,1,A) 
  REFORMAT FIELDS=(F1:1,12,F2:1,3) 
  SORT FIELDS=COPY
/* 

Steps 1 & 2 are simply inserting a control field at the end of the record, which can then be used as the JOINKEY in Step 3.

In this example do we actually need the first 2 steps? Anyways the 12th and 4th column are spaces in both the input files.

I can understand that this has got somwthing to do with the input record length. Just thought of asking you.

Aaru,

I guess that's to generate a key in both the files which will result in a match for all the records. Unless you have something like that, you need those 2 steps. But in this particular example(instream input) I guess it's not really needed. But when it comes to "real" files, you may not have such a key in both the files which has the same value for all the records.

Arun is correct. In this particular example, inserting the control field is not necessary, but I was trying to provide a jobstream that could be easily modified for "real world" situations.

Sasikumar,

Do you want only the matching records into the output? What about the non-matching entries in both the files(not shown in your example)?

Hi Arun,

Thanks for reply. my output file should have for each entry in file 1 all the entries of file 2 having matching variable 4 and variable 5 in file 1 with variable 2 and variable 3 in file 2. If there is no match with file 2 then i dont need the that entry at all. hope this is clear.

Sasikumar,

You can use the below Syncsort job to achieve this.
Code:
//STEP1  EXEC PGM=SORT               
//SORTJNF1 DD DSN= File1
//SORTJNF2 DD DSN= File2
//SORTOUT  DD DSN= Output file               
//SYSOUT   DD SYSOUT=*               
//SYSIN    DD *                       
  JOINKEYS FILES=F1,FIELDS=(13,7,A)
  JOINKEYS FILES=F2,FIELDS=(5,7,A)
  REFORMAT FIELDS=(F1:1,12,F2:1,11,F1:20,3)
  SORT FIELDS=COPY

Hi All,

I tried running the above code given by Alissa Margulies, but the following is the comppilation error.

code:
-------- PROCESSING SYSIN --------
JOINKEYS FILES=F1,FIELDS=(12,1,A)
E3 - DSS10065E - PARAMETER 'FILES' IS UNIDENTIFIED.
JOINKEYS FILES=F2,FIELDS=(4,1,A)
E4 - DSS10065E - PARAMETER 'FILES' IS UNIDENTIFIED.
REFORMAT FIELDS=(F1:1,12,F2:1,3)
SORT FIELDS=COPY


Pls let me know if this is the error due to SORT utility

Thanks,
Abhishek

Hello,

Are you running Syncsort? If you are running Syncsort, which version? If you are not running Syncsort, you will probably not be able to use JOINKEYS.

Did you submit the job or simply run it thru some jcl checker? If you did not submit the job, do so.

Hello,

While the sort products have many similarities, they also have quite a few differences.

If you start a new topic in the DFSORT part of the forum and describe your input files and relevant fields and what you want as output, someone may be able to show you a way to to what you need without joinkeys.

Joinkeys are the "facility" from SyncSort.

sasikumar1984,

The purpose of those steps is already explained in this thread. Initially you tried a "keyless" matching which requires overlaying keys explicitly before matching. But your second requirement really had keys to match.
