Thanks all!

Aratti, I ended up using your algorithm, but I fixed a few errors to make it work. Here's the code I ended up with:

W[0] = (Ocount * 6) + Tcount dig 0
W[1] = (Ocount * 3) + Tcount dig 1 + W[0] dig 1
W[2] = (Ocount * 5) + Tcount Dig 2 + W[0] dig 2 + W[1] dig 1
W[3] = (Ocount * 5) + Tcount Dig 3 + W[0] dig 3 + W[1] dig 2 + w[2] dig 1
W[4] = (Ocount * 6) + Tcount Dig 4 + W[1] dig 3 + W[2] dig 2 + W[3] dig 1
W[5] = W[2] dig 3 + W[3] dig 2 + W[4] dig 1
W[6] = W[3] dig 3 + W[4] dig 2 + W[5] dig 1
W[7] = W[4] dig 3 + W[5] dig 2 + W[6] dig 1

Thanks again
Joe
