PARTIAL2 With Modifier (NYSIIS) - trillium_discovery - trillium_quality - 17.2

The NYSIIS modifier is used with the PARTIAL2 routine to match two (2) strings, using an algorithm based on a standard NYSIIS algorithm.

Improved NYSIIS Algorithm

1. If there are any numerics in the string, return a blank code.
2. Blank out all non-alphabetic characters.
3. If the string is all blanks, return a blank code.
4. Capitalize all letters in the string.
5. Translate the following first character(s) of the string:

   From characters	To characters
   MAC	MCC
   KN	NN
   K	C
   PH and PF	FF
   WR and RH	RR
   DG	GG

6. Translate the following last character(s) of the string:

   From characters	To characters
   S or Z	Blank
   EE or IE or YE	Y
   DT or RT or RD	D
   NP or ND	N
   IX	IC
   EX	EC
   JR or SR	Blank

7. Set the first character of code with the first character of the string.
8. Translate the following character(s) that occur after the first character string:

   From characters	To characters
   EV	AF
   E, I, O, U	A
   Y	A, when not last character
   Q	G
   Z	S
   M or KN	N
   K	C
   PH	FF
   H	Replace with preceding character when preceded or followed by a vowel.
   W	Replace with preceding character when preceded by a vowel.
   SCH	SSA when SCH is at end of string, or, SSS when SCH is not at end of string.
   SH	SA when SH is at end of string, or, SS when SH is not at end of string.
   GHT	TTT
   DG	GG
   WR	RR

9. Add letter to code if not same as preceding letter of code; do this until a 10 character code is created or until the string has no more characters.
10. Change the last letter(s) of code:

    From characters	To characters
    S	Blank
    AY	Y
    A	Blank

    Table 1. Scoring for NYSIIS Modifier

    Score	Description
    100	Codes are equal (excludes blank versus blank).
    80	Blank code versus blank code.
    75	Blank code versus non-blank code.
    0	Code is not equal.
