Difference in compilation of a vbcode in cscript command and visual studio

Question

I have the following code in visual basic , which I am running through visual studio .

    Module Module1

        Sub Main()



            On Error GoTo errorHandler
            Dim oLapp As Object
            Dim oItem As Object

            oLapp = CreateObject("Outlook.application")
            oItem = oLapp.createitem(0)
            '
            With oItem
                .Subject = "A MAIL"
                .To = "[email protected]"
                .body = "2018 RUSSIA IS OURS"
                .Send
            End With
            Console.Write("KROOOOOOOOSSSSSS")
            Console.Read()
            'Set oLapp = Nothing
            'Set oItem = Nothing

    errorhandler:
            Console.Write("jkjk")
        End Sub

End Module

This code is purported to send an email through outlook . However , I thought of doing this through command prompt and I got to know about "cscript" command which is used to run VB scripts in windows command prompt .

So , I put the following code in an notepad file and saved it with .vbs extension . Then when I tried calling this file using cscript , I got an error . It said syntax error at line 7 , col23 .

That line turns out to be :

On Error goto Errhandler 

As such I commented that line out and tried running again and got an error again in line 8 , stating "expected end of statement .

So , I thought cscript might still be supporting "set" and "let" and hence put set in line 8 and I got the same error again .

So , is there any difference in the compilation of visual basic code in both these places . What will be the equivalent code of the code presented here that can be run via cscript and perform the task of sending an email through outlook .
