    This COBOL program is simple and easy to understand. It correctly displays the message “Welcome to Our Bank” without any errors. The structure is clear, and the use of the DISPLAY statement is appropriate. It is a good example for beginners to learn basic syntax. However, the program is very basic and does not include any advanced features or real-world functionality. Overall, it works correctly and is useful for understanding the fundamentals of COBOL programming.
