I want to know if it is possible to check or control an array's size to avoid errors in code before using this array.
How can I check the array's size ?

I am searching something like: if array.length > 0 then....

Thanks !

Code:

if len(array) >= 5 then
    array[4] = 9
endif

Depending on what you are doing there are other reasonable approaches

Code:

redim(array, 5)
array[4] = 7

Code:

check error
    array[4] = 5
on error
    _ClearException()
enderr
