Open arrays were in Delphi from the beginning, but Dynamic arrays were added much later (circa 4.0 IIRC.) Object Pascal was always a lot more free with setting the bounds of an array too - you could specify any arbitrary range or even an enumeration. That's one thing I miss in C like languages. Being able to define an enumeration, then set the array bounds to that type - and then access it via the enumeration's values. On a side note, I also miss sets. They were a first party part of the language, not a set of bolted on classes in the runtime library. I remember that I would quite often defined an enumeration, and array that used that enumeration as the subscript and a set to allow parts of the enum to be turned on and off when accessing the elements of the array. That was pretty cool. It made certain things a lot simpler - like defining errors that were raised by an action and then getting their textual error messages - all without having to do any conversion or anything fancy.
