A constant is a named item that retains its value throughout all operations. The value ПЂ, or 3.1415926535, is an example of a numeric constant; the letter A is an example of a character constant.

You can create compile-time constants that exist throughout the operation of a Visual FoxPro application. You can use a constant and know that its value doesn't change during the operation of your application. At design time, you can effect a change throughout an application by changing only the value of a single constant.

A constant can contain any data type value.

For information about defining and undefining constants, see How to: Define a Constant.
