Looper, List Box, Combo Box and Table control

Empty property used in the arrays and in the associative arrays

• If an array or associative array is empty (Empty property returns True).
  Example:
  
  // Associative array of file sizes
  aaFileSize is associative array of int
  ...
  IF aaFileSize.Empty = False THEN
  Info("The array contains at least one element")
  END
  
• Whether an element of an associative array exists or not. For an associative array without duplicates, the Empty property is set to False if the element exists. For an associative array with duplicates, the Empty property is set to False if at least one element exists.
  Example:
  
  // Associative array of integers
  // indexed on strings and with duplicates
  aaIDPerCustomer is associative array of int
  // Add the identifier of customer "A"
  aaIDPerCustomer["A"] = 55
  // Add the identifier of customer "B"
  aaIDPerCustomer["B"] = 321
   
  IF aaIDPerCustomer["A"].Empty = False THEN
  Info("At least one element A exists")
  END
