====== CONST ======

//Since version 0.9//

Syntax:

  const <varname> = <number>
	
The ''CONST'' directive defines a constant. The constant can be subsequently used as a regular variable, except that it is read-only.

Constants of any numeric types (bytes, integers or floats) may be defined. The number must be a numeric literal (no expression is allowed here).

Example:

  const BORDER = $d020
  const WHITE! = 1
	
  poke BORDER, WHITE!
  
  const PI% = 3.1415926
