I Feel Like A Dork For Asking But Here Goes.

[Bokkie]

Can anyone tell me what I'm doing wrong with this code? It's the first time I've ever tried to use an array in AutoIT. I need to pass an array into a function. The function needs to redim it according to whatever I need it to return. I've tried various code changes but I can't get it to compile without errors. The main procedure does not know how much is coming back so is it right to configure it as $mylines[1] if only to ensure it is an array?

I also thought arrays were 1-based but it gives me this error: C:\Temp\Test.au3 (9) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:

Help appreciated.

dim $mylines[1]
TestArray($mylines)
Exit

func TestArray(byref $mylines)
    redim $mylines[3]
    $mylines[1] = "ABC"
    $mylines[2] = "DEF"
    $mylines[3] = "GHI"
    Return
EndFunc

dim $mylines[1]
TestArray($mylines)
Exit

func TestArray(byref $mylines)
    redim $mylines[4]
    $mylines[0]; not being used
    $mylines[1] = "ABC"
    $mylines[2] = "DEF"
    $mylines[3] = "GHI"
    Return
EndFunc

dim $mylines[1]
TestArray($mylines)
local $i
for $i = 0 to ubound($mylines) - 1
msgbox(0,"",$mylines[$i])
Next
Exit

func TestArray(byref $mylines)
    redim $mylines[4]
    $mylines[0] = "?????"; not being used
    $mylines[1] = "ABC"
    $mylines[2] = "DEF"
    $mylines[3] = "GHI"
    Return
EndFunc

In your reply you said that [0] not being used. I can assign to [0] so when your comment said not being used is that by convention?

no it was by what code you supplied

or I could have resassigned your orignal array i.e.

dim $mylines[1]
TestArray($mylines)
Exit

func TestArray(byref $mylines)
    redim $mylines[3]
    $mylines[0] = "ABC"
    $mylines[1] = "DEF"
    $mylines[2] = "GHI"
    Return
EndFunc

Incase you missed why that didn't work...

In your code you had redimmed the array to have 3 elements.

redim $mylines[3]

The array spots you made by doing that are:

$mylines[0]

$mylines[1]

$mylines[2]

When you tried to stick something into $mylines[3], autoit didn't know what you were talking about. Hense the error.

Thanks guys. I understand that ok now. I see it's C-style, 0-based and not 1-based as I thought it was - for some daft reason that only a dork would assume!

The array now works as I was hoping it would.
