Like most programming languages, VBScript lets you store data in variables. A variable may be thought of simply as a named location in memory where data may be stored. VBScript is what is known as a loosely typed language, which means that a particular variable may store any kind of information, be it a number, a piece of text, a date, or some more complicated chunk of data (as opposed to strictly typed languages where you can only store one kind of information in each variable). Before you can use a variable, though, you must declare it; that is, you must let ASP know that you want to create a variable with a particular name.
One great feature of ASP is Web Services. Web services mean that you can literally have several pieces of your application on different servers all around the world, and the entire application will work perfectly and seamlessly.
