Some specifications are needed before working: 1. Same number of records in both files. 2. No duplicated record(more than one same id) If the speed is important, then suggest a JCL script and forget the COBOL programming Thank you!
File1 - key - 101 File2 key - 1000 x 101 , 1001 xx 101 , 1003 xx 101 need all records from 2 after compare with file1 and rest of all same type of records. How?
Thank you for this very useful video!
VERY VERY WELL EXPLAINED.THANKS a lot..
Nice explanation 👏
Superb expain
Thank you
What if there are - Number of records in file1 - 20 and Number of records in file2 -12 . How does the EOF concept work here..
If the EMP-ID filed is alphanumeric then how can we validate the records?
It is about sorting, still gt and lt works

Comparison mostly goes on considering key is unique and u r right, key mostly be unique
What if file1 has 7 records and file2 has 10 records
File1 - key - 101 File2 key - 1000 x 101 , 1001 xx 101 , 1003 xx 101 need all records from 2 after compare with file1 and rest of all same type of records. How?
