- The dBase IV Ver 1.1 (DOS) manual has the algorithm for getting
- the Soundex code for a string. This is how you do it...
-
- 1. Retain the first letter of the name.
- 2. Drop all occurrences of the letters (a e h i o u w y) in all
- positions except the first
- 3. Assign a number to the remaining 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 two or more adjacent letters have the same code, then drop all
- but the first letter
- 5. Generate code of the form "letter digit digi digit" - add trailing
- zeroes if there are less than three digits, and drop all digits after
- the third one on the right
