This section will discuss the fundamentals of VBScript and define concepts such as datatypes, loops and others.

VBScript Data Types

VBScript contain only one data type called a Variant. A Variant is a special type of data type which can contain distinct kinds of information, based on how it is used. Since Variant is the only data type in VBScript, this is also the data type returned through all functions in VBScript.

At its simplest, a Variant can have either string or numeric information. A Variant acts as a number while you employ it in a numeric context and string while you employ it in a string context. That is, if you are working along with data that looks like numbers, VBScript suppose that it is a number and does whatever is most suitable for numbers. Likewise, if you are working with data which can only be string data, VBScript treats it like string data. Always you can make numbers behave as strings through enclosing them in quotation marks (" ").
