Redefining variables within a For-To loop?

[Quinch]

What would be the best way to do it? I have a loop set up thusly -

Func Inet_Cleanup()
For $x = 1 To UBound($inet)-1
  $inet_info = InetGetInfo($inet[$x], -1)
  ;If the download was complete and successful
  If $inet_info[2] = True And $inet_info[3] = True Then
   InetClose($inet[$x])
   _ArrayDelete($inet, $x)
   $x = 1
  ;If the download was complete and unsuccessful
  ElseIf $inet_info[2] = True And $inet_info[3] = False Then
   ConsoleWriteError("Download error: "&_ArrayToString($inet_info)&@CRLF)
   InetClose($inet[$x])
   _ArrayDelete($inet, $x)
   $x = 1
  EndIf
Next
EndFunc

- but I eventually hit an array range exceeded error.

Which makes sense. When you're going from 0 to MaxIndex and deleting, you're lowering the the index value of the array on each loop.

Easiest solution, go backwards.

#include <Array.au3>
Dim $asInet[5] = ["1", "a", "2", "b", "3"]
_ArrayDisplay($asInet)
For $i = UBound($asInet) -1 To 0 Step -1
 ConsoleWrite($asInet[$i] & @CRLF)
 _ArrayDelete($asInet, $i)
Next
If Not IsArray($asInet) Then ConsoleWrite("No longer an Array!")

Go from last to first element.

For $x = UBound($inet)-1 To 1 Step -1
....
Next

Ah - so the Ubound($inet) is evaluated once, not every time the loop runs?

Quinch,

Yes, the limits are set by the For statement and are not revaluated during the loop.

Alright, that's one mystery solved, then. Thanks for the help.
