Hi All,

I have a requirement to extract the file, I used Key file as a FB file of 20 LRECL and the data file as 4096 LRECL VB file. The actual data is only 4092 and 4 byte is RDW.

My keys are @ first 10 position in both the Key and the data file. I used SORT to match between these two files and extract the data. Below is the sort Card.

Code:
JOINKEYS FILES=F1,FIELDS=(1,10,A)                               
JOINKEYS FILES=F2,FIELDS=(5,10,A)                               
REFORMAT FIELDS=(F1:1,20,F2:1,4096),FILL=X'FF'                   
JOIN UNPAIRED                                                 
SORT FIELDS=COPY                                                 
OUTFIL FILES=01,
  INCLUDE=(25,2,BI,NE,X'FF',AND,1,2,CH,NE,X'FF'),
    OUTREC=(25,4096)
OUTFIL FILES=02,
  INCLUDE=(1,2,BI,NE,X'FF')
    OUTREC=(25,4096)


In this in my input file, 1000 is the maximum length of the file, but the total length was defines assuming that we might get additional data for that file.

When I tried to execute this match, I got my matched / extracted record to O/P file, but the o/p file is filled with X'FF' till the rest of the record after 1000 position. Could you please advise me what I missed here.

Many thanks,
HK

Your job is a mess!

Assuming you want output file1 to contain the records from F2 that have a match in F1, and you want output file2 to contain the records from F2 that do not have a match in F1, you can use the following DFSORT job:

Code:

//S1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//IN1 DD DSN=... input file1 (FB/20)
//IN2 DD DSN=... input file2 (VB)
//F2MATCH DD DSN=...  output file1 (VB)
//F2ONLY DD DSN=...  output file2 (VB)
//SYSIN DD *
  JOINKEYS F1=IN1,FIELDS=(1,10,A)
  JOINKEYS F2=IN2,FIELDS=(5,10,A)
  REFORMAT FIELDS=(F2:1,4,?,F2:5)
  JOIN UNPAIRED,F2
  SORT FIELDS=COPY
  OUTFIL FNAMES=F2MATCH,
    INCLUDE=(5,1,CH,EQ,C'B'),BUILD=(1,4,6)
  OUTFIL FNAMES=F2ONLY,
    INCLUDE=(5,1,CH,EQ,C'2'),BUILD=(1,4,6)
/*


As an example, if input file1 contains:

Code:

AAAAAAAAAA     F1R1   
CCCCCCCCCC     F1R2   
DDDDDDDDDD     F1R3   
GGGGGGGGGG     F1R4   


and input file2 contains:

Code:

rrrrBBBBBBBBBB     F2R1 XXXXXXX
rrrrCCCCCCCCCC     F2R2 XXXXXXXXXXXXXXXX
rrrrGGGGGGGGGG     F2R3 X
rrrrHHHHHHHHHH     F2R4 XXXXXX


Then output file1 will contain:

Code:

rrrrCCCCCCCCCC     F2R2 XXXXXXXXXXXXXXXX
rrrrGGGGGGGGGG     F2R3 X


and output file2 will contain:

Code:

rrrrBBBBBBBBBB     F2R1 XXXXXXX
rrrrHHHHHHHHHH     F2R4 XXXXXX


If that's NOT what you're trying to do, then you need to explain more clearly what you are trying to do with an example of input and expected output.
