A single exit point will obviate the need to duplicate this clean up code in the error-handling routine.       Error Handling in Nested Procedures & The Resume Statement  

This statement does not specify 0 as the start of the error-handling routine even though a line numbered 0 may be present in the procedure. Now labels are used.

End Sub The code works This causes an error (9 - Subscript Out Of Range), and the code jumps to the error handling block which creates the sheet, correcting the problem, and resumes execution at the If you do not regenerate the error in the called procedure whose enabled error handler is incapable of handling the error, the error may cause the macro to stop or continue

Whenever an error occurs, code execution immediately goes to the line following the line label. The compiler would still jump to it when appropriate.
