VBScript Promblem with using wscript.shell

Hello everyone
i am using a software name MCPS. and there is a possibility to write a script in this program. the scripts from this program contains the extension .mbs and not .vbs
creating wscript object doesn't make a problem but when using there commands for example the name of file or directory ..etc
i come with this error:
wscript is not defined
so is there any way that i can call or get this object
for example when use :
Set objXL = GetObject(,"Excel.Application")
its working . i have tried to GetObject(,"WScript.shell") but it giving me another error related to activeX error activex component can't create object
please help. thanks
the script is :
