====== POKE ======

Syntax:

	poke <int address>, <byte or int value>

The ''POKE'' command stores a value into the given memory address. The following type conversions are possible:

  * ''address'' will be recognized as an unsigned integer
  * if ''value'' is an integer, it will be truncated to a byte

Examples:

  rem ** turn border to black **
  poke 53280, 0
  	
  rem ** unsigned conversion **
  let x = -5
  poke x, 0
  rem ** which will effectively be the same as:
  poke 65531,0
  
  rem ** values are truncated to 8 bits - the MSB is discarded **
  poke 53280, 65535
  rem ** will be the same as
  poke 53820, 255
