Moving from C (not C++) to AS3

Question

I'm moving some of my older C code (see below) to AS3, and
have a couple of areas which I am researching how to convert, and
wonder if anyone can assist?
To give some context to the code below, "appearances" are
when actors (game objects) are introduced into a game level, and an
appearance is defined by an actor number, plus an X and Y position.
A game level can be a title screen, the main game, game-over
screen etc.
For each level in the array levelAppearancesInfo, there is a
pointer to another array containing details of the actual
appearances, plus the number of appearances in that level.
So in a nutshell, I'm looking to find out how to convert to
AS3, from C, the following:
(1) arrays of structs
(2) an array containing a pointer to another array
I do know that references will be replacing the pointers, and
that classes will take the place of structs.
I'm working on this right now, and any insights would be most
appreciated.
The original C code is below that I wish to convert to AS3:

Answer 1

With my second question, it seems that something like:
var array1:Array = new Array(1, 2, 3, 4, 5);
var array2:Array = new Array(6, 7, 8);
var array3:Array = [array1, array1.length, array2,
array2.length];
is on the way towards a solution, but I wonder if there is
anything more elegant.
I could even split it into two parallel arrays - one array
containing references to the arrays, and another array containing
their lengths.
If anybody has any advice regarding my two questions in the
first post, any help would still be most appreciated.
