A variable is used to store information.
If the variable is declared outside a procedure
it can be changed by any script in the ASP file. If the variable is declared
inside a procedure, it is created and destroyed every time the procedure is
executed.

Lifetime of Variables
A variable declared outside a procedure can be accessed and
changed by any script in the ASP file.
A variable declared inside a procedure is created and
destroyed every time the procedure is executed. No scripts outside the procedure
can access or change the variable.
To declare variables accessible to more than one ASP file,
declare them as session variables or application variables.
Session Variables
Session variables are used to store information about ONE
single user, and are available to all pages in one application. Typically
information stored in session variables are name, id, and preferences.
Application Variables
Application variables are also available to all pages in one
application. Application variables are used to store information about ALL users
in a specific application.
