You and Andrew inspired me to try again. How about this?
squashit: func [line [string!]] [
trim/all lowercase line
poke line 1 to-char uppercase to-string line/1

I've been a rebol novice for too long! Someone else commented
recently on how difficult it seems to be to move beyond simple to
advanced. Every script I try seems to center around "foreach" and
. I can tell by reading this list that there's more to life...
if my function is ok, poke is what I needed.
