Creating Constants

You can create user-defined constants in BSL using the Const statement. Using the Const statement, you can create string or numeric constants with meaningful names and assign them literal values.

For example:

Const MyString = "This is my string."
Const MyAge = 49

Note:

The string literal is enclosed in quotation marks ("") . Quotation marks are the most obvious way to differentiate string values from numeric values.

The following examples illustrates the use of the creating constants:

Example 1:

Const MyString = "This is my string." 'Defines a string constant.

Example 2:

Const MyAge = 49 'Defines a numeric constant.

Example 3:

Const Pi = 3.14159, E = 2.71828, Gravity = 9.81 'Defines multiple numeric constants.

Example 4:

Const Greeting = "Hello,"
Const Name = "Alice"
Dim WelcomeMessage
WelcomeMessage = Greeting & Name   'Combines string constants.
'WelcomeMessage   'has string value: Hello, Alice
