Hi
I have two VSAM files. I need the data from one file to be copied to other. If i want to copy the whole file i can use 9f33 option. But i need to copy only one field data to my another file.
For eg
Flie1 has the fields cusno orderno and ownerid
File 2 has the fields cusno partno and secureid
The data are different in both the files
Now i want only the cusno of file2 to be copied in cusno of file1
Hope am clear. |

What is it?
If your shop has DFSORT, use the following with few modifications as per your layout -
| Code: |
//VSAMCOPY EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SORTIN DD DSN=FILE2,DISP=SHR assumption lrecl=80,recfm=fb
//SORTOUT DD DSN=FILE1,DISP=MOD layout similar to FILE1
//SYSIN DD *
OPTION COPY
OUTREC FIELDS=(1,5, * assumption CUSNO starts @1 length 5
80:C' ')

There can be many ways ,one of them is
I assume cusno as unique key in both the VSAM
A simple COBOL program will do it.
Open file 1 in I-O and file 2 in input mode.
Read both the files based on the cusno ,though they are VSAMs read them sequentially and compare
If file1.cus-no =file2.cusno
Read file1,file2
Else IF file1.cusno > file2.cusno
Write Record from file2
Read file 2
Else If file1.cusno < file2.cusno
Read file1 |

Hello,
For you to get usable suggestions, it would be a good idea to post a few records from each file and what the output of this process will be.
Your test tada needs to show what happens when the "same" key is in both files and when it is present in one file but not the other.
Your output file should show the data after the process completes. |
