Get Var from a function

[AutoitMike]

Is there a way to get a variable that is created within a function?

In this example I get a message box with "pp", I am expecting "abc"

Global $a

$a="pp"

Test($a)

MsgBox(0,"",$a)

Func Test($a)

$a="abc"

EndFunc

Thanks

Hi AutoItMike,

either

Global $a
$a = "pp"
Test()
MsgBox(0, "", $a)

Func Test()
    $a = "abc"
EndFunc   ;==>Test

or

Global $a
$a = "pp"
Test($a)
MsgBox(0, "", $a)

Func Test(ByRef $a)
    $a = "abc"
EndFunc   ;==>Test

Global $a
$a= "pp"
MsgBox(0,"",test($a))
Func Test($a)
$a = "abc"
Return($a)
EndFunc

Global $a
$a= "pp"
MsgBox(0,"",test($a))
Func Test($a)
$a = "abc"
Return($a)
EndFunc

The OP implies the Global $a should be changed. ByRef was the better example, or modify yours to something like:

Global $a = "pp"
$a = Test($a)
MsgBox(0, "", $a)

Func Test($Input)
     If $Input = "pp" Then 
          Return "abc"
     Else
          Return $Input
     EndIf
EndFunc
