Converting long string to individual words in Red/Rebol

Question

How can a string with a sentence be converted to a series of words, e.g. convert following string to:

str: "This is a sentence with some words"

to a series of:

["This" "is" "a" "sentence" "with" "some" "words"]

There seems to be a split function in Rebol3 but no such function in Rebol2.

I tried following code with parse but it does not work:

str: "This is a sentence with some words" strlist: [] parse str [ some got: " " (append strlist got) ]

Error is:

** Script Error: Invalid argument: got

How can this be achieved (a method with parse will be preferable)?

In Rebol 2, you split using PARSE: parse "foo bar baz" " " — rgchris

convenience feature, not recommended or available in rebol3 or red — Geeky I

In Rebol 2, this would be:

str: "This is a sentence with some words" parse str none

resulting in:

["This" "is" "a" "sentence" "with" "some" "words"]

As mentioned in the comments on your post, the documentation. Parse has two modes, one of which is string splitting.

Rebol 3, split will work.

It will be

split str " "

Where split is function. First argument is your string, and second — delimiter.

This does not work in Rebol 2.7.8. ** Script Error: split has no value

Can't find documentation for Rebol 2. In Rebol 3 should work: rebol.com/r3/docs/functions/split.html
