Syntax
... matches( val = text regex = regex [
case = case ]
[off = off ] [len = len ] ) ...

Effect
The predicate function matches
compares a search range of the argument text , defined using off and len , with the regular expression specified in regex . A corresponding logical value is returned. The return value is true when the whole search range matches the regular expression. The comparison is case-sensitive by default, but this can be overridden using the parameter case
.

Note
The match function match can be used to return a subfield that matches a regular expression.

Example
