<blush> I've been extremely busy here and I've got a little time for this - first - a disclaimer - I whipped up that code in preperation for implementing it for a client. But my partner ended doing the functionality with perl. Furthermore, I've deleted much of *this* thread from my mailer. Let me suggest that you just play with compose for a bit, without your target in mind. Just a have a bit of fun with it. What compose allows you to do is to create a data structure, evaluate it as much as you like and change values within that data structure targeted by parenthesis. Since I am not myself an expert with compose, and if I don't write rebol for a week, I get behind the curve even more, let me propose a problem and perhaps the solution will edify me and help you: Here's the problem, define a block with a parenthesized word and evaluate it as a place holder names: ["Tim" "Carlos" "Kai"] == ["Tim" "Carlos" "Kai"]
>> template: [My name is (name)]
== [My name is (name)]
>> foreach name names[print compose template]
** Script Error: name has no value ** Near: name ;; I *don't* know the solution myself, but finding it will be most helpful for ;; both of us cheers tim
