Please use the Code tags to preserve formatting.

Bear in mind that your "600" will being in column 81. Is that the problem?

What are the RECFMs of your inputs?

Run this, please. If you see anything needing to be in hex, display it in hex. Either way, paste it here.

Code:
JOINKEYS FILE=F1,FIELDS=(1,3,A)
JOINKEYS FILE=F2,FIELDS=(1,3,A)
JOIN UNPAIRED,ONLY
REFORMAT FIELDS=(F1:1,7,F2:1,7)

it tells absolutely nothing about the product You are using

to provide the proper answer we NEED TO KNOW THE BRAND of Your Sort product

SYNCSORT issues WER... messages
DFSORT issues ICE... messages

while providing the same overall functionality each of them has its own quirks

so ... what is the sort product You are using ???

If you had no 600 in your output before, then I'd guess you have a "pre-defined" or "defined in the JCL" output file, which is not taking account of the size of your REFORMAT record.

Since you got a failure with -3nadh's suggestion, you may even have other problems with your files.

Check that your inputs are both FB.

Check that your output is not pre-defined nor defined (LRECL/RECFM) in the JCL to let Sort set those values, or ensure instead that they are 80 and FB.

If you leave the REFORMAT off, I expect you'd then get the output you expect, even though you may have to review it for "usefulness".

I think you have been around long enough to know that PGM=SORT is not specifying the actual sort product but an alias. Look at the messages. They will tell you which sort product you are using. There are differences between Syncsort and DFSort - and DFSort questions are posted to the DFSort part of the forum whilst, for some reason, Syncsort questions are in the JCL section.

Hi,

Try this

Code:
JOINKEYS FILE=F1,FIELDS=(1,3,A)                   
JOINKEYS FILE=F2,FIELDS=(1,3,A)                   
JOIN UNPAIRED,ONLY                                 
REFORMAT FIELDS=(F1:1,7,F2:1,7),FILL=X'00'         
SORT FIELDS=COPY                                   
OUTREC IFTHEN=(WHEN=(8,7,CH,EQ,X'00'),BUILD=(1,7)),
       IFTHEN=(WHEN=(1,7,CH,EQ,X'00'),BUILD=(8,7))


It will be great help to forum members if you post all required info

Regards,
Chandan

Chandan,

Checking 8,1 & 1,1 in Outrec should suffice

rajkumarmf1985,

Looking back, you show your sample data in sorted order. If it is actually like this, specify SORTED on the JOINKEYS for each file that is in order.

You could have gotten your answer from the very first post of Bill, if you could read that carefully enough.

You've coded
Code:
DCB=(RECFM=FB,LRECL=80,BLKSIZE=27920)
in your JCL, so you won't see "600" in output, which is at position 81.

Again the second hint from Bill, could have told you why "600" did not appear in output with your first Job in this thread but, you said,"600 is populated at column 8".

If you've inputs strictly as what you've posted, try this:

Code:
//JS001   EXEC PGM=SORT         
//*                             
//SYSOUT   DD SYSOUT=*           
//*                             
//SORTJNF1 DD *                 
100                             
200                             
300                             
400                             
//SORTJNF2 DD *                 
100                             
200                             
400                             
600                             
//*                             
//SORTOUT  DD SYSOUT=*           
//*                             
//SYSIN    DD *                 
  SORT FIELDS=COPY               
  JOINKEYS FILE=F1,FIELDS=(1,3,A)
  JOINKEYS FILE=F2,FIELDS=(1,3,A)
  JOIN UNPAIRED,ONLY                   
  REFORMAT FIELDS=(F1:1,3,F2:1,3)       
  OUTREC OVERLAY=(1,80,SQZ=(SHIFT=LEFT))
/*                                     
//*                                     
You'll get, what are you looking for. You could use BUILD as well, though I leave that as an exercise.

SORTOUT RECFM INCOMPATIBLE
SORTOUT : RECFM=FB ; LRECL= ; BLKSIZE=
From the manual,
Quote:
if a REFORMAT control statement is not provided and ONLY the unpaired records from both join inputs are requested, the resultant records will be variable-length, regardless of the record formats of the join input data sets, and the record length will be the maximum of any fixed-length input file record length plus four (for an RDW) and any variable-length input file record length.

So if you get rid of DCB on SORTOUT and submit your Job again, you won't get that error.

errr..rr but the "600" will be at 81st posistion and it won't appear the way you want.

Without the REFORMAT and for UNPAIRED,ONLY, both F1 and F2 records will appear in the same position.

After all that, TS will have no clue as to which record comes from where, so I'm reluctant to expend much effort on this :-)
