How to create empty arrays? How to delete arrays?

[MonsieurOUXX]

Hi all,

I have 2 questions :

1/ I don't know how to create an array that contains zero elements at first.

the code below is invalid :

Local $array[0]

the code below doesn't produce any output :

Local $array
_ArrayAdd($array, "1")
_ArrayAdd($array, "2")
_ArrayDisplay($array)

2/ I don't know how to delete an array

I'd like to remove all the contents of an array at once to make it brand new.

1 - For what? (It is impossible)

2 - I use ReDim:

#include <array.au3>

Dim $array[10]

$array[0] = 5

$array[8] = 7

_ArrayDisplay($array)

ReDim $array[1]

$array[0] = ""

ReDim $array[10]

_ArrayDisplay($array)

For...pretty much everything! (it is a nonsense to have an array that HAS to contain something when created - it's possible in most other languages)

2 - I use ReDim:

Cool, thanks.

i use something like this to make empty arrays, not sure if thats what you are looking for

you'll just have to delete empty array at the end or you'll have a blank at the top

Dim $Array[1][2] = [[""]]

Dim $Array[1][2] = [[""]]

Interesting. Thanks!

Interesting. Thanks!

It's unnecessary because when an array is created all the elements are set to '' without you having to do anything.

Also Redim doesn't delete arrays, it resizes them. Just declare the array again and the old values will be lost.
