hi Terry, << Here's one feature I could use.. Find/whole n: "This is a bookmark" find/whole n "book" ==false >> How about something like:

== none --Gregg

Aye, that works, but then requires parsing n, perhaps for the second time, which can be slow, especially on really really big docs. I prefer inserting and appending a space to the word... a: "book" insert a " " append a " " n: "This is a bookmark" find n a == none Just thought this would make a nice addition to "Find"... "Find/whole". Text editors have a "Find whole words" ability... so should Rebol. TBrownell

Well, but: nn: "But this is a book; this is yet another book, and finally, this is a book" a: "book" insert a " " append a " " find nn a == none So you probably shouldn't add spaces, but parse with a charset! that's the complement of all letters that may constitute a word. And finally check if the string starts or ends with the word you're looking for. ~H

What's wrong with just using:

>> find "This is a bookmark in a book of writing" " book "

== " book of writing" In other words, just put a space before and after the search item? Or if you're using more complex text, something like:

>> parse/all Text [any [[[#" " | #"^/"] mark: "book" end: [#" " | #"^/"]]

(print copy/part Mark End) | skip] end] book == true Andrew Martin ICQ: 26227169 http://valley.150m.com/
