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 SCALE_FACTOR:Float=1.5
Const DEFAULT_TITLE:String="Mark Sibly"

Multiple constants may be declared per Const statement using the comma separator.

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.
