Dictionary.count()
Dictionary.count
A Number-type property. Returns the number of keys in the dictionary (by their nature all keys are discrete so there is not potential of duplication in the count). If:
$MyDictionary = {cat:animal; dog:animal; rock: mineral};
$MyNumber = $MyDictionary.count;
MyNumber is now 3.
Dictionary.count and Dictionary.size are interchangeable. Use which ever seems more intuitive.
