array permutation

hi,
i have a tricky problem. i have for example three arrays of different dimestion

A =[1,2,3,4]
B=[5,6,7]
C=[8,9]

i would like to generate all the different combinations of values in these arrays and the values inside the array should not be repeated.

e.g. the resultset should be

1,5,8
2,5,8
3,5,8
4,5,8
1,6,8
2,6,8
3,6,8
4,6,8
1,7,8
2,7,8
3,7,8
4,7,8
1,5,9
2,5,9
3,5,9
4,5,9
1,6,9
2,6,9
3,6,9
4,6,9
1,7,9
2,7,9
3,7,9
4,7,9

any idea how to do this for any number N of arrays?
Thanks!!

VB Code:

Dim A(1 To 4) As String
Dim B(5 To 7) As String
Dim C(8 To 9) As String
A(1) = "1"
A(2) = "2"
A(3) = "3"
A(4) = "4"
B(5) = "5"
B(6) = "6"
B(7) = "7"
C(8) = "8"
C(9) = "9"
For x = 1 To 4
    For y = 5 To 7
        For z = 8 To 9
            Debug.Print A(x) & "," & B(y) & "," & C(z)
        Next
    Next
Next

Thanks for the input:) i figured out how to do it for a small number of cases by using FOR loops. but how would you do it if you have N arrays without having to write N FOR loops?
Thanks
