- | Returns the Soundex equivalent to a character string ("string" may be a CHARACTER or C STRING column, or a string literal). The algorithm used by this function is identical to that applied to keywords in MDK index using the ;SX option. The routine only pays attention to the first 24 characters of the input; the return value is C STRING length 25. | + | Returns the Soundex equivalent to a character string ("string" may be a CHARACTER or STRING column, or a string literal).

Note that the $SOUNDEX function does not parse fields, and therefore returns the Soundex equivalent of the entire string. For example, the Soundex equivalent of "Dynamic Information Systems Corporation" is "DNMKNFRMTNSSTMSKRP". | Note that the $SOUNDEX function does not parse fields, and therefore returns the Soundex equivalent of the entire string.
