Specifying Constant Scope

A Const statement can specify scope the same way a variable declaration can, and the same rules apply:

To create a constant that exists only within a procedure, declare it within that procedure, using only the Const keyword.
```
Const conPi = 3.14159
```
To create a constant that's available to all procedures within a given module but not to any code outside that module, declare it in the declarations section of the module, using the Private keyword before Const.
```
Private Const conMax = 4096
```
To create a constant that's available to all modules in all workbooks, declare it in the declarations section of the module, using the Public keyword.
```
Public Const conMin = 0
```
As with any other type of data, public constants are available only in the workbook where they're declared and in any workbooks with a reference link to the workbook where they're declared. In addition, you can limit the scope of a public constant to a single workbook by using the Option Private Module statement in the module where the constant is declared.
