Hi ,
I need help with a file compare logic in COBOL.

2 Files.
FileA - No duplicate keys
ex:
10
20
30
40
Fileb - Duplicate keys
10
10
10
30
30
30

Ouput :
All matching records in fileb with filea and records in filea and not fileb
10
10
10
20
30
30
30
40

Could you please help me with this code.

Thanks,
Vijay

Vijay,
Are you sure Cobol is the way you need. This will be simple and clean to do it in a JCL and use the files in the program. This topic is very frequently discussed in the forum and a search can give you all the code and options available.

Thanks for the reply.I looked at the logic ,looks like the logic works only if both the files have unique records.For me filea has unique records and fileb has duplicates

Thanks,
Vijay

Vijay,

Did you look at the link posted by me? If you looked at it then with minor changes it will fit for your requirement.Both easytrieve and cobol solutions need just a minor change.
