Data Types:
• VBScript supports only one data type called ‘Variant’.
• The variant data type is a special kind of data type that can contain different kinds of information.
• It is the default 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 it is used in a numeric context and as a string when used in a string context.
• Subtypes of data that a variant can contain:
– Empty, Boolean, Integer, Long, Single, Byte, Double, Date Time, string, Object, Error.

Variant intentionally contains no valid data. | Null |
Contains either True or False. | Boolean |
