Sure!  Be glad too...
   The Soundex function creates a phoenetic code based on an input

   key value according to the following rules:

	1) Always retain the first letter of the key.

	2) Drop out A, E, I, O, U, Y, W, and H.

	3) Assign the following numbers to the remaining similar-sounding
	   sets of letters:

		B, F, P, V = 1
		C, G, J, K, Q, S, X, Z = 2
		D, T =3
		L = 4
		M, N = 5
		R = 6

	4) If there are insufficient letters in the key to complete the
	   code, fill with zeroes.

	5) Drop adjacent equivalent letters (e.g. KELLY = K400).

	6) Drop out adjacent equivalents of the first letter (e.g. 
	   LLOYD = L300).
