Post by vijayb » Thu Feb 18, 2010 12:14 pm

Hi,
I need to compare 2 files.for example
File 1:(Key 1 to 4)
1111AAAAAAA
2222BBBBBBB
4444DDDDDD

File2:(Key 1 to 4)
11119998
22229999
44449997

Output:read record from file 1 and compare with file 2.if matching found then pick 5 to 8 posion value from file 2 and replace in file1(position 1 to 4)

9998AAAAAAA
9999BBBBBBB
9997DDDDDD

It's not clear if you've described your requirement completely. I don't want to give you a solution and then have you come back and say "but that doesn't take care of this situation" (which you didn't tell me about).

What is the RECFM and LRECL of each input file?

Does every key in file1 have a match in file2 as shown in your example? If not, please show a better example without every key matching.

Can input file1 have duplicates within it?

Can input file2 have duplicates within it?

If either file can have duplicates within it, please show a better example of input and expected output including duplicates within that file.

Also please run the following DFSORT job and show me the //SYSOUT messages so I can tell what level you're at:

Code: Select all

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