Try something like:
Digit: charset "0123456789"
str: "abcdefgh 09/11/2001 xyz"
Date: [
copy Day 2 Digit #"/" copy Month 2 Digit #"/" copy Year 2 4 Digit
]
Telephone: [
copy Number [
3 Digit #"-" 3 Digit #"-" 4 Digit
]
]
parse str [
Date | Telephone | skip
]

Yes. It's been requested to feedback that more interesting arguments be
supported.

'parse is nicer to use, once you use 'skip. :-)
