Multiple nested loops, if error then jump to the next loop iteration of the topmost loop

I have multiple nested For loops. Is there a way to jump to the next iteration of the topmost main For loop if there is an error in one of the nested ones?

Example:

For $i = 0 to 10
    For $j = 0 to 7
        For $k = 0 to 5
            If @error Then
                "exit this $k loop as well as the $j loop, skip the rest of the $i loop's code and start over with the next $i"
            EndIf
        Next
    Next
    "rest of the code to be avoided if there's an @error"
Next

I know about ExitLoop, so escaping the $k and $j loops is easy but how do I avoid the code that comes after the two nested loops?

Sure, I could set a bool var and do a simple If Then like this...:

$loopError = false

For $i = 0 to 10
    For $j = 0 to 7
        For $k = 0 to 5
            If @error Then
                $loopError = true
                ExitLoop 2
            EndIf
        Next
    Next
    If $loopError = false Then
        "rest of the code"
    EndIf
Next

...but I suspect there must be another, prettier solution.

   ConsoleWrite($i & @CRLF)
   For $j = 0 to 7
      For $k = 0 to 5
         If $i = 4 Then SetError(1)
         If @error Then ExitLoop
      Next
      If @error Then ExitLoop
   Next
   If @error Then ExitLoop
Next

 

Well that's the thing, i don't want to exit the $i loop, i want the next iteration. In other words, if the script is on $i = 5 and there's an error, I want it to go right to $i = 6.

Try ContinueLoop.

Jesus, I'm stupid. I was checking ContinueLoop in the documentation but for some reason gathered it was not what I wanted at all :-D

Anyways, thanks Brew!

It's ok, because the help file doesn't mention For loops in the description.
