    Declare $white outside the loop if you want to access it from outside the loop - eg. declare it where you declare $self. See Coping with Scoping.

      Good idea but i can't . Because my variable takes a screenshot for a moment of my test's progress. I just want to retrieve it outside my loop. I added some code following if this helps

        Sure you can: you declare the variable prior to entering the loop and populate it within the loop. Then you can access it after the end of the loop. 
        my $var;
for my $c (1..10) {
     $var++;
}
print $var;   # prints 10
