Bug ID: 49439
           Summary: Printing and scanning software for Brother L2540DW
                    fails to install (VBScript parser can't handle a "case
                    else" statement with a comment and no statements to
                    execute)
           Product: Wine
           Version: 5.11
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: vbscript
          Assignee: wine-bugs@winehq.org

WINEDEBUG=+vbscript
To reproduce:
1. Run `winetricks mfc42`
2. Run the Brother Printing Device setup program
3. When asked for the connection type, select "Wired Network Connection
(Ethernet)" and be sure to check "Custom Install"
4. When asked how to locate the printer, type in the IP address 127.0.0.1 (this
is just for debugging, any IP address is fine)
After that, a message pops up that says "An error occurred during the
installation" and the software to scan a document over the network is not
installed.
Console output with WINEDEBUG=+vbscript is attached which indicates failure
parsing a VBScript file. I dumped the full text of the file and this is the
problematic part:
select case lcase(PortType)
case "raw"
                 oPort.Protocol      = 1
case "lpr"
                 oPort.Protocol      = 2
case else
'
' PutInstance will attempt to get the configuration of
' the device based on its IP address. Those settings
' will be used to add a new port
'
    end select
oPort.HostAddress   = oParamDict.Item(kHostAddress)
It seems that Wine's VBScript parser can't handle a "case else" clause that
contains nothing but a comment.
