The S7 modifier is used with the RSOUNDEX1 routine to ensure compatibility with Series 7. The S7 modifier applies the same algorithm as in Series 7 to RSOUNDEX1 routine. Use S7 when you want to obtain the same linking results as Series 7. See SOUNDEX1 Routine With Modifier (S7) for algorithm. The input strings are reversed before the algorithm is performed.
Note: All SOUNDEX related routines are limited to working with attribute sizes of 256
characters. If the attribute length exceeds 256 characters, the algorithm will be applied
to the first 256 characters for all SOUNDEX routines. The algorithm will be applied to the
last non-blank 256 characters for all RSOUNDEX routines.
