Re: Quick ?

It�s represent "not"; 0 represents FALSE; and not 0 represents TRUE;

$quit = 0;
while ( ! $quit ){        # means "while not 0", that means "while not
false", that means "while true"
    any statement;
}

Try this test:

#BEGIN OF CODE

$count = 10;
$quit = 0;
while (! $quit)  {            # "not 0" represents "not false" or just
"true", making the "while loop" to be active
    print $count, "\n";
    $count--;
    if ( $count == 0 ) {
        $quit = 1;                # "not 1" represents "not true" or just
"false", making the "while loop" to stop
    }
}
print 'Press ENTER to quit', "\n";
$etc = <STDIN>;

#END OF CODE

What is the ! doing in this statement?

$quit = 0;
while (! $quit)

Thanks
