I guess what u r searching for is the alternative to sever.createobject.
use object tag to create the object, and to use it u must either have progID or clsID.
see if it helps
Object Tag
RUNAT=SERVER ID=YourObjectName
CLASSID="Clsid:1621F7C0-60AC-11CF-9427-444553540000">
End of Object tag
Best Luck..
