Flexible Multidimensional arrays, Ie: [0,[0,0]]

[Rraney]

I can get around this, but its messy. Is it possible receive and array from a function that would have arrays inside it?

The kicker is, I have no idea how large the returning array will be when it is returned.

example return array: [4, ["This, "is", "a", "Test], 2, ["o", "kay"]]

yes... here's a simple example

#include<array.au3>
Dim $array = ReturnArrayOfArrays()
Func ReturnArrayOfArrays()
    Dim $ReturnArray[2][2]
    $ReturnArray[0][0] = 1
    $ReturnArray[0][1] = 2
    $ReturnArray[1][0] = 3
    $ReturnArray[1][1] = 4
    Return $ReturnArray
EndFunc   ;==>ReturnArrayOfArrays
For $x = 0 To 1
    For $y = 0 To 1
        MsgBox(0, "Element [" & $x & "][" & $y & "]", $array[$x][$y])
    Next
Next

If I understand the question right I think this code shows making arrays as elements of another array can be done and an example of it:

#include <Array.au3>

Func AofA()
    Dim $array = _ArrayCreate( 0 )
    
    For $iter = 0 To Int( Random( 0, 10 ) )
        Local $temp_array = _ArrayCreate( 0 )
        
        For $iter2 = 0 To Int( Random( 0, 10 ) )
            _ArrayAdd( $temp_array, $iter2 )
        Next
        
        $temp_array[0] = UBound( $temp_array ) - 1
        
        _ArrayAdd( $array, $temp_array )
    Next
    
    $array[0] = UBound( $array ) - 1
    
    Return $array
EndFunc

$myArray = AofA()

For $i = 1 To $myArray[0]
    _ArrayDisplay( $myArray[$i], "$myArray[ " & $i & " ] of " & $myArray[0] & " elements." )
Next

Hope that helps....

cameronsdad, I don't think that is what the OP wants.

Rraney, yes, you can store an array inside an array element but in order to access the "nested" array you have to copy it into another variable:

Global $Array[2]
Global $SubArray[4] = [ "Red", "Yellow", "Orange", "Blue" ]

$Array[0] = "Foo"

; This stores SubArray inside $Array[1]
$Array[1] = $SubArray

; If we want to access $SubArray, you have to copy it out to a variable
Global $SubArray2 = $Array[1]

For $i = 0 To UBound($SubArray2) - 1
    MsgBox(4096, "", $i & "=" & $SubArray2[$i])

Edit: Of course, once you build $Array, you could just return it from a function like normal.

Hi,

my 2 penneth of what is requested...???

;ArrayOfArays.au3
#include<array.au3>
dim $ar_ArrayL1[1]
_StringSplit($ar_ArrayL1,'[1][2,3,4][3][4,5][6,7]',"][",1)
_ArrayDisplay($ar_ArrayL1,"")
dim $ar_Array[ubound ($ar_ArrayL1)]
for $i=1 to ubound ($ar_ArrayL1)-1
    $ar_Array[$i]=StringSplit($ar_ArrayL1[$i],",")
    _ArrayDisplay($ar_Array[$i],"$ar_ArrayL1[$i]")
Next

Func _StringSplit(byref $ar_Array,$s_String, $Separator, $i_Flag)
    $ar_Array=StringSplit(StringTrimRight(StringTrimLeft($s_String,1),1), $Separator, $i_Flag)
EndFunc

Wow That is exactly what I needed!

I was having a Devil of a time trying to access the array(s) inside the returned array.

ok... this may look real bad... but

whats wrong with my theory here???

#include<array.au3>
#include<string.au3>

Dim $ReturnArray[5]

    
    $ReturnArray[0] = 4
    $ReturnArray[1] = StringSplit("This, is, a, Test",",")
    $ReturnArray[2] = StringSplit("o, kay", ",")
    $ReturnArray[3] = StringSplit("This, is, another, Test",",")
    $ReturnArray[4] = StringSplit("well, done", ",")

For $x = 1 To $ReturnArray[0]
    For $y = 1 To $ReturnArray[$x][0] -1
        MsgBox(0, "Element [" & $x & "][" & $y & "]", $ReturnArray[$x][$y])
    Next
Next

ok... be kind

I am unable to get this code to run under the latest beta.

Valuater, I already answered that in my post. You can not access the elements of the array in that manner. You must copy the contents of the array out to a variable to access the nested array:

#include<array.au3>
#include<string.au3>

Global $ReturnArray[5]


    $ReturnArray[0] = 4
    $ReturnArray[1] = StringSplit("This, is, a, Test",",")
    $ReturnArray[2] = StringSplit("o, kay", ",")
    $ReturnArray[3] = StringSplit("This, is, another, Test",",")
    $ReturnArray[4] = StringSplit("well, done", ",")

For $x = 1 To $ReturnArray[0]
    Global $NestedArray = $ReturnArray[$x]
    For $y = 1 To $NestedArray[0]
        MsgBox(0, "", "$ReturnArray[" & $x & "]" & @CR & "$NestedArray[" & $y & "]" & @CR & $NestedArray[$y])
    Next
Next
