Dim Array with Variable

[v3rt1g0]

I don't understand what I'm doing wrong, and I can't seem to find more info on the proper syntax via the help file or these forums.

What is the proper way to create array elements using a variable containing a number?

If I want to dump data into $aName[1], $aName[2], $aName[$n].. How do I create the array $aName[1] thru $aName[$n], to be later populated as below?

The file the script is reading is created by a resident app that sits on several dozen machines, pushing machine status to a share.

If I run the following, I get this error:

C:\[...]\Studio_Machine_Status\machstat002.au3 (44) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:

$aName[$i] = FileReadLine($oFile, 1)

^ ERROR

I've tried putting a For loop in there to create $aName[1], $aName[2], etc and that doesn't work either.

I must be missing something fundamental here.

#include <Array.au3>
#include <File.au3>

Global $mArray, $i, $sFile, $oFile

UpdateStatusData()

Func UpdateStatusData()
    ;Check folder exists and dump contents to array
    If Not FileExists("\\share\dat\") Then MsgBox(0, "Error", "Can't find \\share\dat\")
    $mArray = _FileListToArray("\\share\dat\", "*.kh", 1)
    If @error = 1 or @error = 4 Then MsgBox(0, "Error", "Path not found or no files found at \\share\dat\")
    _ArrayDisplay($mArray) ;works fine
    ;dim arrays to # of files/machines present
    Global $aName[$mArray[0]], $aStat[$mArray[0]], $aOS[$mArray[0]], $aLang[$mArray[0]], $aIdle[$mArray[0]], $aApp[$mArray[0]]
    ;Populate arrays
    $i = 1
    For $i = 1 to $mArray[0]
        $sFile = $mArray[$i]
        $oFile = FileOpen("\\share\dat\"&$sFile, 0)
        $aName[$i] = FileReadLine($oFile, 1) ;Machine name  <-------------------------- Crash
        $aStat[$i] = FileReadLine($oFile, 2) ;Ready/Running/Dead
        $aOS[$i] = FileReadLine($oFile, 3) ;Which OS installed?
        $aLang[$i] = FileReadLine($oFile, 4) ;which lang OS installed?
        $aIdle[$i] = FileReadLine($oFile, 5) ;how many minutes idle?
        $aApp[$i] = FileReadLine($oFile, 6) ;are any known apps running?
        FileClose($sFile)
    Next
    _ArrayDisplay($aName)
EndFunc

Dim $mArray[100]

replace 100 by the max number of element you'll have.. and do the same for other array variables

If you know how many elements you want before you create the array, then it's just:

$n = 10; number of elements to have

Global $avArray[$n + 1] = [$n]; sets element [0] to the count

For $i = 1 to $avArray[0]

; do something on elements [1] thru [10]

Next

[v3rt1g0]

Global $avArray[$n + 1] = [$n]; sets element [0] to the count

That did it. Thank you!

I see what I was doing wrong.
