Infinite counting loop

10 posts in this topic

For $i = 1 To 10

Send $i

Next

Can you tell me, how can I make this loop not end?

Thank you.

I meant can this count anew after 10?

You don't need nested loops for this

CAUTION - INFINITE LOOP

For $i = 1 To 11
    If $i > 10 Then $i = 1
    ;Send($i)
Next

Here's another version

For $i = 1 To 10
    ;Send($i)
    If $i = 10 Then $i = 0
Next

I would use the While loop posted by kaotkbliss, but it's always good to know which options are available.

Thank you very much. Why would you use the While loop? Edited by SergeySpandaryan

Okay, it's a hunch that's all. I think it might be faster. I'll just test it and see becasue I may be wrong. Back in 5 mins. :)

Yep I was right. Kaotkblis' while loop is faster. Here's the test (run in SciTE).

Global $iLoopCount = 0, $iTimer = TimerInit()

For $i = 1 To 10
    ;Send($i)
    If TimerDiff($iTimer) > 10000 Then ExitLoop
    $iLoopCount += 1
    If $i = 10 Then $i = 0
Next
ConsoleWrite($iLoopCount & @CRLF)

$iTimer = TimerInit()
$iLoopCount = 0
While 1
    For $i = 1 To 10
        ;Send($i)
        If TimerDiff($iTimer) > 10000 Then ExitLoop 2
        $iLoopCount += 1
    Next
WEnd
ConsoleWrite($iLoopCount & @CRLF)

I think the reason is that the While loop is handled internally and runs quicker than keep querying the value of $i in my code. There's not so much in it though.

Yeah the number of loops run in 10 seconds is greater using the while loop. The conditional statement slows the first test down. It's a bigger difference than I thought.
