I did a quick search and found this that might help:
It says WScript.Arguments(0) or WScript.Arguments.Item(0) can be used to access the arguments. You would need to use this in your vbscript.
You might want to test this with some script editor where you can pass arguments, or even call it from command line, like
c:\windows\system32\cscript.exe "C:\folderpath\Program_Filter_Excel.vbs" "vikas"
Once it is set up to use arguments, then you can set up your Start Process as suggested.
That example is not using variables though.
I hope that helps further.
Regards.
