Hi everybody :)
The 1st script below would generate a fatal error after the function calls itself 3799 times (on my computer)


Func aaa()
    If ... Then aaa() ; recursion limit reached if 3799 times True
EndFunc   ;==>aaa

"Recursion level has been exceeded - AutoIt will quit to prevent stack overflow"

The 2nd script below allows to bypass this limit. Is it a recommended way to avoid a possible recursion issue ?


Func aaa()
    While 1
        If ... Then ContinueLoop ; 3799 times isn't a limit anymore.
EndFunc   ;==>aaa

The recursion problem is caused by the requirement to put lots of data on the stack when a function is called - recalling the same function again and again means that the stack rapidly gets filled and AutoIt will quit to prevent an overflow. In your second snippet I cannot see any recursive calls to function aaa(), so there should not be any stack filling and so no recursion problem.

Have you read the Recursion tutorial in the Wiki? It has examples of both good and bad practice to test.
