Array variable has incorrect number of subscripts or subscript dimension range exceeded

[zbatev]

Hello again,

Can somebody please explain this error on this code?

Error: "Array variable has incorrect number of subscripts or subscript dimension range exceeded."

$str = "Sun,Mon,Tue,Wed,Thu,Fri,Sat"
$strarr = StringSplit($str,",",1)
$disp = ""
For $rd = 1 to UBound($strarr)
    $disp = $disp & $strarr[$rd] & @CRLF
Next

I think I can answer my own question, the Ubound function is returning an extra 1 element instead of 7(sunday to raturday) it returns 8.

Went to Help and found this:

Remarks

Remember that the value returned by UBound is one greater than the index of an array's last element!

Hmmmm

Use Ubound this way in this case:

For $rd = 1 to UBound($strarr) - 1

In autoit, and many other scripting languages, arrays typically include and begin with element 0.

So if you did:

$str = "one,two,three" 
$strarr = StringSplit($str,",",1)

Then:

$strarr[0] = "one"
$strarr[1] = "two"
$strarr[2] = "three"

ubound returns the number of elements in the array, so ubound($strarr) would = 3

$strarr[3] gives the error you see because the last element of the array is actually $strarr[2]

This is why you will so often see the code: "ubound($array) - 1" being used.

$strarr = StringSplit($str,",",1)

Then:

$strarr[0] = "one"
$strarr[1] = "two"
$strarr[2] = "three"

StringSplit with flag 1 return the count in the first element and not $strarr[0] = "one".

You would be right if flag was 2 !
