                                         VBScript Data Types
What Are VBScript Data Types?
      VBScript has only one data type called a Variant. A Variant is a special kind of data type that
      can contain different kinds of information, depending on how it's used. Because Variant is the
      only data type in VBScript, it's also the data type returned by all functions in VBScript.

      At its simplest, a Variant can contain either numeric or string information. A Variant behaves
      as a number when you use it in a numeric context and as a string when you use it in a string
      context. That is, if you're working with data that looks like numbers, VBScript assumes that it is
      numbers and does the thing that is most appropriate for numbers. Similarly, if you're working
      with data that can only be string data, VBScript treats it as string data. Of course, you can always
      make numbers behave as strings by enclosing them in quotation marks (" ").
Variant Subtypes
      Beyond the simple numeric or string classifications, a Variant can make further distinctions
      about the specific nature of numeric information. For example, you can have numeric
      information that represents a date or a time. When used with other date or time data, the result
      is always expressed as a date or a time. Of course, you can also have a rich variety of numeric
      information ranging in size from Boolean values to huge floating-point numbers. These
      different categories of information that can be contained in a Variant are called subtypes. Most
      of the time, you can just put the kind of data you want in a Variant, and the Variant behaves
      in a way that is most appropriate for the data it contains.
