Action
Prefix Character—The ampersand character can only be specified as the last character of the string.
If specified by itself, it is used to indicate that no replace function is required on the matched string,
but is used to indicate if the input string matches with the match-string. If it is specified with digits
preceding it, the specified digits are prefixed to the matched string. For examples of the ampersand
character usage, refer to "Ampersand (&)
Can only be specified by itself.
Phrase "none" is used to specify NULL string. Can be used for both match-string and replace-string.
Example 1: match-string=none; replace-string=4692550000; indicates that when input
string is NULL, replace it with 4692550000.
Example 2: match-string=469255; replace-string=none; indicates that if a match is
found, replace the matched string with NULL. If input string is 4692551234, after the
digit manipulation, the resultant string will be 1234.
