Question about loops

[faldo]

I remember a few versions back, i used to get a whole lot of "recursion error" (or something like that) in Do...Until-loops when i had the script running for a few days in a row accessing the loop. I solved the problem by useing While...wend-loops instead but i have one question that still haunts me.

If i have the following loop:

Dim $count=1
Do
    $count=$count+1
    If $count=10 Then
        $count=1
        MsgBox(0, "", "Count is 10")
        NextFunction()
    EndIf
Until @error

Func NextFunction()
;~  blablabla
EndFunc

...will it terminate the loop when i "goto" the next function or will the loop continue in the background? Do i need to use Exitloop just in case, like this:

Dim $count=1
Do
    $count=$count+1
    If $count=10 Then
        $count=1
        MsgBox(0, "", "Count is 10")
        NextFunction()
        Exitloop
    EndIf
Until @error

Func NextFunction()
;~  blablabla
EndFunc

Msgbox(0,'','Some text here')

Try running this, i think you'll have your answer

The loop will not terminated without an error or ExitLoop. Edited March 6, 2009 by Andreik

faldo.

In your first snippet when $count = 10 you will in order: reset $count=1; show the MsgBox(0, "", "Count is 10"); and then run NextFunction(). When NextFunction returns, the Do...Until loop will continue until $icount reaches 10 again, when the whole process repeats. This will go on until @error is set by the returning NextFunction. So continuing passes through NextFunction until it errors.

In your second snippet, when $count = 10 you do the same things in the same order, but when NextFunction returns, ExitLoop will (unsurprisingly) exit the Do...Until loop - i.e. only one pass through NextFunction. Actually, as there is only the one pass, you need not reset $count (because it is never used again within the loop) and the Until @error becomes pretty moot (as the only line which would ever trigger it is $count=$count+1 - and if that forces an error you are in big trouble :-)). In fact, you might as well use a For...Next loop.

I hope this is clear.

P.S. In place of $count=$count+1, did you know you can use $count += 1? Look in the Help file under 'Language Reference - Operators'

I thought the loop would end if i "goto" a functions outside the loop since autoit can't handle multiple "threads". I thought i had to use the "call"-function in order to still run the loop and use a function from within the loop.

I'm glad i got that answered, thanx for the quick reply guys.
