AutoIt: Why can't I insert an element into an array using a function?

[AUTO-IT]

When I call the Bar function, the element is not inserted into the array passed as an argument. Here is my code:

Foo ()


Func Foo ()

    Local $Baz[100] = []

    Call ("Bar", $Baz)

    MsgBox (0, "", $Baz[0])

    Return

EndFunc


Func Bar ($_Array)

    $_Array[0] = 1

    Return

EndFunc

Thank you very much for your help.

Use

Func Bar(ByRef $_Array)

According to the help file:

Quote

The ByRef keyword indicates that the parameter should be treated as a reference to the original. By default the parameter is copied into a new variable but ByRef links the new variable to the original.

It will work as you desire if you change your function declaration like this --

Func Bar ($_Array)

FWIW, you don't need to use Call(). Do this instead --

Bar($Baz)

Did someone talk about ByRef parameter ?
