Constants
Constants can be used to store values that don't change during the execution of your program.
Constants must be declared in your program before use with the Const command. Declaring a constant means defining a name, type and initial value for it.
The general syntax for declaring a constant is:
Const Identifier : Type = ConstantExpression
For example:
Const STARTUP_SIZE = 1000
Const SCREEN_WIDTH = 640, SCREEN_HEIGHT = 480
Const SCREEN_AREA = SCREEN_WIDTH * SCREEN_HEIGHT
Const SCALE_FACTOR:Float = 1.5
Const DEFAULT_TITLE:String = "BlitzMax"
Multiple constants may be declared per Const statement using the comma separator. In Strict mode, if no type is provided for a constant, the constant defaults to being of type Int.
The initial value for a constant may be an expression, but the expression must itself be constant - it may only use other constants or literals and may not use any variables.
