Declaring a variable with a variable...

[mistersquirrle]

I have a script that creates an array, and I want to create a second dimension in the array, with set values, but the amount of variables in the original array can change, and I don't want to have to manually set up creating the second dimension, and get errors, or not having all the variables have a second dimension. This is the manual set up:

Dim $Values[6] = [13, 20, 25, 12, 13, 21]
Dim $Order[6][2] = [[$Values[0], 1],[$Values[1], 2],[$Values[2], 3],[$Values[3], 4],[$Values[4], 5],[$Values[5], 6]]

and this is kinda what I was thinking of having:

For $i = 0 To UBound($Value) - 1
        $Value[$i] = StringReplace($Value[$i], ",", "")
        $Dim &= ", [$Value[" & $i & "], " & $i & "]"
    Next
    $Dim = StringTrimLeft($Dim, 2)
    $Dim = "[" & $Dim & "]" ;This outputs: [[$Value[0], 0], [$Value[1], 1], [$Value[2], 2], [$Value[3], 3], [$Value[4], 4], [$Value[5], 5], [$Value[6], 6], [$Value[7], 7], [$Value[8], 8], [$Value[9], 9]]

    Dim $Dim[UBound($Split)][2] = $Dim

is there any way to do what I'm trying to?

Take a look at the ReDim keyword. It allows you to resize an array, even a 2 dimensional one. Pretty much the only restriction is that you can't change the number of dimensions.

This doesn't do what I want... I don't want to resize an array. I want to create a second dimension, with just 0 - however many array subscripts there are, corresponding to the first dimension array it's being paired with, so I can sort the first dimension, and still know the order of things. Does that make sense? It's kinda related to my previous topic: http://www.autoitscript.com/forum/index.php?showtopic=101352

I am not certain what you are trying to do.

Here is a solution to my best guess.

;
#include <Array.au3>

Dim $Value[6] = [13, 20, 25, 12, 13, 21]
Dim $Order[UBound($Value)][2]
;Dim $Order[6][2] = [[$Value[0], 1],[$Value[1], 2],[$Value[2], 3],[$Value[3], 4],[$Value[4], 5],[$Value[5], 6]]

For $i = 0 To UBound($Value) - 1
    $Order[$i][0] = $Value[$i]
    $Order[$i][1] = $i + 1
Next

_ArrayDisplay($Order);
;

That's actually just about exactly what I was trying to do. Thank you. I wasn't sure how to do that in a for loop, cause I thought it'd just keep redoing the first array subscript. I guess I just needed to test it a bit. Just a bit of tweaking to that, and that'll work just great

I think you mean:

It sounds like you want to create an index array that you will rearrange in order to access the original array.

Local $aArray[300][10]    ; Assuming that you have 300 rows with up to 10 fields per row.
Local $aIndex[300]        ; Index for each row.
Local $I                  ; For-loop control variable
Local $bSwapped           ; Flag used during bubble sort.
Local $sDisplay           ; 

; Read all the data into $aArray here by whatever method you want.

; Set up the index array
For $I = 0 To 299
    $aIndex[$I] = $I
Next $I

; Sorting time.
; We sort not by sorting the original array, but the index array.  This is a version of bubble sort.
Do
    $bSwapped = False
    For $I = 0 To 298
        ; The function OutOfSequence($aArray, $N1, $N2) returns true if $aArray[$N1][*] and $aArray[$N2][*] is out of sequence.
        If OutOfSequence($aArray, $aIndex[$I], $aIndex[$I+1]) Then
            ; Out of order - swap the indexes
            $vTmp = $aIndex[$I]
            $aIndex[$i] = $aIndex[$I+1]
            $aIndex[$I+1] = $vTmp
            $bSwapped = True
        Endif
    Next
Until $bSwapped = False

; The original array remains the same.  The index array $aIndex, gives the order of the array.  
; You could set up multiple indexes based on different sequence criteria.
; To access the records in sequence use the index.
For $I = 0 To 299
    $sDisplay += $aArray[$aIndex[$I]] & ", "
Next
