Defining Your Own Constants

1. You can also define your own constants for use in Visual Basic. The format for defining a constant named PI with a value 3.14159 is:
   
   Const PI = 3.14159
   
   
2. User-defined constants should be written in all upper case letters to distinguish them from variables. The scope of constants is established the same way a variables� scope is. That is, if defined within a procedure, they are local to the procedure. If defined in the general declarations of a form, they are global to the form. To make constants global to an application, use the format:
   
   Global Const PI = 3.14159
   
   within the general declarations area of a module.
