Answer / Mohamad Waseem

Reading the second-last record of a VSAM file without knowing the key can be challenging, but there are ways to achieve this using COBOL:
1. Set up a separate sequence set for the reverse read.
2. Set the initial record as the maximum record number (or one less than it if you want the second-last record).
3. Open the file in sequential access mode and read records in reverse order until you reach the desired record or the beginning of the file.
