That is just a syntax that initializes an array to null. The first
append will be element 0. The statements below are exactly equivalent
in that regard:
dim my
The first element of a REALbasic array has index 0. So to declare an
empty array, you set its upper bound to -1. The UBound function
returns the index of the last element of the array. Thus an array has
1 + Ubound(theArray) elements.

Indeed it is. Whether or not you choose to expose the array itself
is another question -- in the long run, I recommend not doing so --
but getting started is this simple.

RB arrays extend from element 0 to an upper bound, which can be found
at run time by the UBound method.
If you declare an array with (0) it isn't empty - it actual

John,
Thanks alot. Just to confirm: in RB (too) it is as simple as declaring
an array of another object/class within a class?
Thanks again.

Hi Kirt.
You can easily include an array of objects within another object, to
as many levels as you like.
One way is to include a Property in your parent window that is
initially empty, then populate it with new objects as required.
So the property would look like
myEntityArray(-1) as myE
