[Gambas-user] About help and arrays and variables

ok!

i was cofused from two things

1) 
in previous message about static arrays Fabien said that:

so a 
DIM htmpArray as integer[]=  [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
i thought was a static.

and 

2) 
---------------------------------
DIM aInt2 AS Integer[3]

aInt2[0] = 1
aInt2[1] = 20
aInt2[2] = 30

aInt2.Add(40) 'here is the resize of the array
aInt2.Add(50)
aInt2.Add(60)

PRINT aInt2[3]
PRINT aInt2[4]
PRINT aInt2[5]
---------------------------------

In my gambas2-2.21 rev3300 there is no error, nor compilation nor
execution!
