What is the primary purpose of 'On Error GoTo Label' in VBA?

'On Error GoTo Label' is a Visual Basic for Applications (VBA) statement used for structured error handling. Its primary purpose is to redirect the program's execution flow to a specified section (a label) within the same procedure when a runtime error occurs. This allows the developer to implement custom error-handling logic, such as displaying informative messages, logging error details, cleaning up resources, or attempting to recover from the error, instead of letting the program crash or display a generic VBA error message.
