End Sub

Benefits of Using “Go To” in VBA

1. Error Handling: The “Go To” statement is often used in conjunction with error handling. It allows you to jump to an error-handling routine when an error occurs.
2. Code Navigation: It helps in navigating through large blocks of code, making it easier to manage and understand.
3. Efficiency: By skipping unnecessary code, you can make your VBA procedures more efficient.

Common Use Cases for “Go To” in VBA

1. Error Handling: Directing the flow to an error handler.
2. Conditional Execution: Skipping over code blocks based on certain conditions.
