Hiding a batch file with a bvs script , need help

[abispac]

Hi guys, im stting up a cab wih a simple gameand would like to use xp instead of dos so i can use the hardware on the motherboard,anyway i set up things this way, i created a batch file that calls another batch file, converted the first file to an exe file, use instant sheller to hide windows and to call the exe file that calls the batch file, and it works like a charm, boot superfast, the only downside its that you can see the autoexec file wile its executing mame, for about 5 seconds, so all i want its to hide that window , i found a way to do that , with a vbs script,

Set WshShell = CreateObject("WScript.Shell")
WshShell.Run chr(34) & "C:\mame\autoexec.bat" & Chr(34), 0
Set WshShell = Nothing

And when i tried to run the script i get this error

script: c:\mame\invisible.vbs
line:    1
char:   1
error:   invalid character
code:   800A0408
source: microsoft vbscript compilation error

i was wondering if someone can help me fix this, i do not want to use a front end for this, as the game itself boots superfast, and dont want a fe logo before the game, thats the point, to make it feel original, thanks alot for any help.
