How to: Define a Constant

A constant can contain any data type value.

To assign a value to a constant

Use the #DEFINE preprocessor directive.

In the following example, the constant TABLERR1 is defined as a character string.

	Copy Code
#DEFINE TABLERR1 "This table is not available. Please try later."

In an application, wherever you would normally specify the character string "This table is not available. Please try later." you can use TABLERR1 instead.

To release a defined constant

Use the #UNDEFINE preprocessor directive.
Copy Code
#UNDEF TABLERR1
