You cannot explicitly declare a variable to be of type Class. In the VBScript context, the term "class object" refers to any object defined using the VBScript Class statement.

Once you have created a class definition using the Class statement, you can create an instance of the class using the following form:

Dim X
Set X = New classname

Because VBScript is a late-bound language, you cannot do any of the following:

Dim X as New classname

-or-

Dim X
X = New classname

-or-

Set X = New Scripting.FileSystemObject
