I have a record in file 1 as
Key Value
47 111111111
47 22222222
47 33333333

I have a record in file 2 as
Key Value
47 11111111
47 22222222
47 33333333

In the output File I want the records as

Key Value_file1 Value_file2
47 111111111 222222222
47 111111111 333333333
47 222222222 111111111
47 222222222 333333333
47 333333333 111111111
47 333333333 222222222

If the key in file1 matches with the one or more records in file2 then display the key of file1 with the combination of value in file2

ie if file1 has a key 42 and value 10
file 2 has 2 records with key 42 but different values. then we need to display

file1_key(42) file1_value(10) file2_value
file1_key(42) file1_value(10) file2_value

Does this explain....

Can someone help me out

Sorry I forgot to mention one point

If a key is found only in file1 and not file2 then I donot want it in the output file

Your example has the same key for every record in both files. This makes it very difficult to understand your "rules". Does every record in your files really have the same one key? Can file1 really contain duplicate keys within it? Can file2 really contain duplicate keys within it? Please show a better example of input and output with more keys showing all of the possible variations, and give a better explanation of the "rules". Also, give the RECFM and LRECL of the input files.

Yes file1 and file2 can contain duplicate keys and I think Thompson has given the rules for it

Key Value
42 100000
42 200000
43 300000
44 400000
45 500000

Key Value
42 100000
42 200000
43 400000
45 500000

So the Output should contain
Key Val_fil1 Val_fil2
42 100000 200000
42 200000 100000
43 300000 400000

PLEASESEE IF THIS HELPS

William,

It doesn't help me or answer any of my questions. If it helps you, then perhaps you can provide the solution.

Ok I will pu it again..

File1 has one or more records with same key but different values

File2 has one or more records with same key but different values

If a key in File1 matches with one or more key values in File2 but both have a different value we put it in the output File with each combination of values.

If a key in File1 matches with File2 but both have same value we do not put in output file

What would the output be if the input were:

File1
42 100000
42 200000
42 300000
42 400000
43 320000

This is nothing but 1 to 1 search

You take one record from file one and compare with all the records in file2 with same key

If key matches and value changes you put into output file else we skip

This happened only in highlighted set

Output
KEY Val_F1 Val_F2
42 100000 150000
42 100000 250000
42 100000 350000

42 200000 250000
42 200000 350000
42 200000 400000

42 300000 150000
42 300000 250000
42 300000 350000
42 300000 400000

Ah, I see. I don't know of a way to do that with DFSORT/ICETOOL.

Thanks Frank

I achieved the above task.
Sorry for al the confusion.

I used the sort utility followed by an easytrieve program to get that results.

With z/OS DFSORT V1R5 PTF UK51706 or z/OS DFSORT V1R10 PTF UK51707 (Nov, 2009), you can now use JOINKEYS to do this kind of thing. For example:

Code:

//S1    EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//IN1 DD DSN=...  input file1
//IN2 DD DSN=...  input file2
//SORTOUT DD DSN=...  output file
//SYSIN    DD    *
  JOINKEYS F1=IN1,FIELDS=(1,2,A),SORTED
  JOINKEYS F2=IN2,FIELDS=(1,2,A),SORTED
  REFORMAT FIELDS=(F1:1,2,F1:3,7,F2:3,7)
  OPTION COPY
/*


For complete details on JOINKEYS and the other new functions available with the Nov, 2009 DFSORT PTF, see:
