Change variable

[Andreik]

Example:

$VAR = 9
$VAR = $VAR + 1
$VAR = $VAR - 1

Is a way to know if $VAR was changed, even if $VAR value is 9, after add and diff operations?

There is no native event for that, but you could do it for yourself easily by declaring a Global flag, like $fChanged, and setting it to True in any code that change the monitored variable:

HotKeySet("{ESC}", "_Quit")

Global $fChanged = False
Global $Var = 9

AdlibEnable("_Update", 5000); Update every 5sec

While 1
    If $fChanged Then
        MsgBox(64, "Change", "Variable changed!")
        $fChanged = False
    EndIf
WEnd

Func _Update()
    $Var += 1
    $Var -= 1
    $fChanged = True
EndFunc

Func _Quit()
    Exit
EndFunc
