select case bug ,format code

When encountering a procedure call starting with 'Do' in SELECT CASE, the subsequent code is forcibly indented during code formatting and treated as if it were a do while loop.

```
SELECT Case "ABC"
                 DoSUB1()
                       Case "KE2"

need:
SELECT Case "ABC"
                 DoSUB1()
            Case "KE2"
```
