Ok, never mind, it looks like parse does exactly what I want... thanks. I
did want to turn \" into " after breaking it up, however.
Odd that parse recognizes backslashes for escaping quotes where the rest of
REBOL uses ^ for escaping purposes....

Okay, that's nice, but I want to parse real text, not a block. I'm just
going to use repeated replace statements here (since the original goal was
to replace [red] with an escape character followed by "[31m" for example),
but I was hoping to go through the various color tags ([red], [green],
[blue] etc.) and search through the remainder of the text after finding a
tag regexp-style for the next tag. That way, no time would be wasted
re-scanning through the entire string to find new codes... but a repeated
replace is okay as well. C'est la vie.

More or less. I've found enough of a solution. <g>
