How to automate rumba through Excel VBA

Dear members of the forum,

I'm trying to automate Rumba mainframe through Excel VBA. I'm quite new to this.

I tried the following code to open mainframe application but it throws "ActiveX component Can't create object" error.

Dim oSys As Object

Set oSys = CreateObject("rumba.system")

 

Can you please guide? If you have existing code samples, that would be very helpful for me to understand and proceed further.

Note : I'm using MicroFocus Rumba Desktop 9.4.1
