 From my point of view (and after having experimented with it for a 
while) I found that some hints in the help seem to be misleading.

:-)

Don't know if my sun shines bright enough to heat away that fog, but 
what I would do is

DIM my_array as NEW SHORT[]

To add something to the array at its end, you will use

my_array.Add(xx)

and to clear the stuff completely, you may use

my_array.Clear

The drawback is that for having a 4096 cells big array you will have to 
add 4096 values first. (On the other hand, when you use a fixed-size 
array like you did above, you will have to write 4096 zeros to get rid 
of its values...)

But be aware that poking something into a certain position of it just 
will need a

my_array[x] = y

In my programs, much of the stuff in the help about STATIC, PRIVATE and 
so on works different from how it's explained, but this may be due to 
the fact that I use modules rather than classes (I found that they react 
differently here).
