Hello,
In your program read each record and move it to working-storage. When the AT END condition is raised, the record in working-storage is the last record. If you want to know the logical record number also put a counter in working-storage and add 1 each time a record is moved to working-storage.

Thanks Dick. . Is there any possible to get the last record by using high values concept in COBOL program?

If the file is sequential, the answer is no -- you must read every record to reach the last record.
If the file is VSAM KSDS, being accessed from CICS, and you put a HIGH-VALUES record into the file, you can use READPREV to get to the last record. Batch VSAM access does not support read previous, though, so if you're using a batch program then you must, again, read every record to read the last record.
