anchor.diff:  Syntax:	ARR READ variable list
   
   Examples:
  +
   	100 ARR READ A
   	110 ARR READ B, C
   	120 ARR READ D(15)
  
positive.code: Notice that the number of values in a READ statement do not have to match the number of values in DATA statements.
  You may READ in pairs and define ten values per DATA statement.
  You may READ ten items from DATA statements that contain one value each.
  READing more values than are specified by DATA statements, in total, will cause an error.
  BASIC keeps an internal pointer to the next data item.
  This pointer can be reset with the RESTORE statement.
  
  
negative.code: Syntax:	LET target variable [, target variable...] = expression
  
  Examples:
  
  	40 LET A = 0
  	50 LET B = A + 10
  	55 LET C = C + 1
