Thats why i much prefer to use something like the Parse dialect that comes with Rebol / Red - http://www.rebol.com/docs/core23/rebolcore-15.html

Here's ebiester Icon example in the parse dialect:

    s: "This is a string"

    parse s [
        any " "                         ;; skip past any leading blanks (none in this example!
        any [                           ;; repeat ANY while keeps matching (true)
            copy word to [" " | end]    ;; next word up to next blank or EOL
            (print word)                ;; print word
            skip                        ;; skip past blank
        ]
    ]

And here is one translation of falsedan example:

    ws:     [some [" " | "^-"]]
    sep:    #"^-"
    digits: charset "1234567890"
    lower:  charset [#"a" - #"z"]
    upper:  charset [#"A" - #"Z"]
    cost:   [3 5 digits "." 2 digits]
    quoted-description: [
        copy quot [{'} | {"}]
        some [{\} quot | upper | lower | " "]
        quot
    ]
    unquote-description: [to sep]
    description:         [quoted-description | unquote-description]
    SKU:                 [some [upper | digits]]

    parse/case s [ws cost sep description sep SKU ws]
