There are two kinds of arrays in [[Gambas]]. One is well-documented, the other barely-documented.
==Native Arrays==
A "native array" is an array of other variable types; see [http://gambasdoc.org/help/cat/arraydecl Array Declaration] for documentation and examples.
==Array Class==
The Array class is an abstract class, which is to say that you cannot use it directly; you have to create a descendant class which implements it and has a public _new() procedure. (Classes have a public _new() procedure by default, so you don't actually have to declare this.)

To inherit from the Array class, simply put "inherits Array" in the class before declaring any functions or procedures. (Actually, I'm not sure if it ''has'' to be first, but it seems like good form to have this near the top.)

Once declared, your descendant class will have all the methods and functions defined in the [http://gambasdoc.org/help/comp/gb/array?v3 Array] class.
