Array stops being an array?

[Gar]

So I have a bit of complex code that runs normally for awhile, then, at some point, the array I'm using blanks to nothing. (just "" and not an array)

I have very few interactions with the array, so I can't figure out why this is happening. I have some _ArrayPops, but I put two 'null's at [0] and [1] and stop the pops if they are 'null'... but it's still happening. I also have some ByRefs passes.

Does anyone know if there's a common bug or something that can blank an array?

Gar,

Arrays usually behave unless you remove all the elements (which you say you do not) or you redeclare them a a simple variable. If you posted your code we might be able to offer more pertinent advice.

GEOSoft - look away now!

When you post code please use Code tags. Put [autoit] before and [/autoit] after your posted code.

Cool thanks for the tag info, am sort of newbie here.

This area MUST be the problem but I can't discern exactly how.

$Array = _ArrayCreate("Null", "Null")

;some other function adds elements to the array, then:

For $count = UBound($Array)-1 to 2 step -1
    If $Array[$count] = "Null" Then
        Return
    EndIf
    $event = _ArrayPop($Array)
Next

This eventually results in the array being popped to zero... but shouldn't this work?

Gar,

- 1. Why use the UDF function when you can create arrays by merely declaring them?

- 2. Return is for exiting functions - you need ExitLoop to escape from the For...Next loop.

- 3. If you stop your loop at 2 you will never check the Null values - remember that arrays start at element [0].

This should work for you:

#include <Array.au3>

Global $Array[2] = ["", ""]

;some other function adds elements to the array, then:

For $count = UBound($Array) - 1 To 1 Step -1
    If $Array[$count] = "" Then
        ExitLoop
    EndIf
    $event = _ArrayPop($Array)
Next

_ArrayDisplay($Array)

All clear?

Ah, thank you! A couple things I never knew Thanks for the info, it worked!
