You receive a runtime error related to file handling in your COBOL program. How would you approach debugging this issue, and what tools or techniques would you use?

Runtime errors related to file handling in COBOL programs often stem from issues such as incorrect file permissions, invalid file paths, or file access conflicts. To debug this issue, one would start by checking the file permissions and access rights to ensure the program has the necessary permissions to read from or write to the file. Additionally, examining the file handling code, ensuring proper file open/close operations, and using file monitoring tools or file system debuggers can help identify and resolve file-related runtime errors in COBOL programs.
