[Solved] ArraySearch doesn't work when using $array[0] = 0

[algiuxas]

Hello everybody, so I might found a bug in _ArraySearch:
 

#include <Array.au3>
Local $abc[2] = ["b", "b"]
$h = "+---------------------------------+" & @CRLF
ConsoleWrite($h)
For $i = 0 To 1
    $abc[0] = 0
    out()
    $abc[0] = 1
    out()
    $abc[0] = -1
    out()
    $abc[0] = "Abc"
    out()
    $abc[1] = "Hello"
Next
Func txt()
    Return "$abc = [" & $abc[0] & ", " & $abc[1] & "]" & @CRLF & _
            "> _ArraySearch($abc,""Hello"") = "
EndFunc   ;==>txt
Func shouldoutput($ans)
    Return "_ArraySearch Should return:  " & ($ans ? 1 : -1)
EndFunc   ;==>shouldoutput
Func out()
    ConsoleWrite("> " & txt() & _ArraySearch($abc, "Hello") & @CRLF & "> " & shouldoutput($abc[1] == "Hello") & @CRLF & $h)
EndFunc   ;==>out
Exit

Sorry for this messy script

Yeah, I can't even begin to interpret what you are trying to accomplish here.  But first thing that needs to be clarified is WHICH parameter you believe is throwing the error when set to 0.  But even given that, I notice that your _Arraysearch function uses the default values in the script you provided, so I am not sure what you are saying is broken.

You can see it returns incorrectly when the first array value is 0.

Sometimes it would help when one first dumb things down to the basics to show their issue.

Have a look at this and see if you can figure out why you get your "error":

#include <Array.au3>
Local $abc[2] = [0, 1]
ConsoleWrite('_ArraySearch($abc, "ABC") = ' & _ArraySearch($abc, "ABC") & ' >Error code: ' & @error & @CRLF)
ConsoleWrite('_ArraySearch($abc, 0) = ' & _ArraySearch($abc, 0) & ' >Error code: ' & @error & @CRLF)
ConsoleWrite('_ArraySearch($abc, 1) = ' & _ArraySearch($abc, 1) & ' >Error code: ' & @error & @CRLF)
ConsoleWrite('_ArraySearch($abc, "ABC", Default, Default, Default, 3) = ' & _ArraySearch($abc, "ABC", Default, Default, Default, 3) & ' >Error code: ' & @error & @CRLF)
ConsoleWrite('_ArraySearch($abc, 0, Default, Default, Default, 3) = ' & _ArraySearch($abc, 0, Default, Default, Default, 3) & ' >Error code: ' & @error & @CRLF)
ConsoleWrite('_ArraySearch($abc, 1, Default, Default, Default, 3) = ' & _ArraySearch($abc, 1, Default, Default, Default, 3) & ' >Error code: ' & @error & @CRLF)
