HURRA! You did it! [Smile]

(Even if it was at the cost of processor muscle: you're wasting loads of cycles, going through 4 times as much (96 vs 24) permutations as needed, but it DOES work! And it does comply with the requirements! [Smile] )

{edit} I did some timing: 30 calculations in 3'2" equals aprox. 10 calculations per minute...
If we consider 10.000 possible 4 digit numbers, we'd need (on my PIII@1.1GHz) aprox. 1.000 minutes to go through all the combinations!
That amounts to almost 17 hours!!! So, figuring this one out is out of the question!!! {/edit}
