Yes i did. But i try to understand.

Thanks Fabien!

So

1) PRIVATE aInt1[3] AS Integer
is an embedded array of integers with 3 elements in an object for
example FMain.

2) DIM iFieldr AS NEW Integer[9]
is a static array of integers with 9 elements 

3) Also PRIVATE Languages AS String[] = [ "fr", "it", "es", "de", "ja" ]
is a static !!!
(so far i thought that this was a dynamic array, because it was declared
with no dimensions PRIVATE Languages AS String[])

4) A dynamic array has global reference, where is it declared ?

A dynamic array declaration how is it?

Example?


ps:
so far i knew that 
1) a static array has fixed dimensions, cannot be resized
2) a dynamic array can be resized, has no static dimensions. 
so i thought a 
DIM aInt AS Integer[5] is a static
and
PRIVATE aInt AS Integer[] is a dynamic 

but i saw that in both declarations i can do

aInt.Add(6) and to add elements.

The terminology of static and dynamic is different in Gambas or i am
wrong again?
