I have two strings that are identically formatted and will each pass the same regex. I am interested in how to get the below code working with the '/g' modifier. 

$s1 = "45 20 00 00 00 03 00";
$s2 = "40 20 00 00 00 00 00";

while ((@a = $s1 =~ /(\d{2})/g) && (@b = $s2 =~ /(\d{2})/g)){
        print "found $a[0] and $b[0] !!!\n";
}

It seems to not be starting back at the last position found as the loop continues indefinitely and only gets the first 2 values. 
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
found 45 and 40 !!!
...
continues until i break

Any ideas?

Thanks!
