When an If...Then...Else statement becomes too long, you can replace it with a Select...Case Statement.
You can use the short form for short, easy tests. There are not many statements that can be used with this form. They include assignment, method call, Call, Call Event, End, Exit, GoTo Case, ReDim, Return, and Throw.
