With all due respect to present company, perhaps it's due to the fact that continuations are not that well known. TRY covers some of the common uses, but there are still interesting applications (I think of things like Rugby...) Again, just for my own edification, I'd really appreciate anything anyone has on how that was done/appeared in 1.x. -jn- -- ; sub REBOL {}; sub head ($) {@_[0]} REBOL [] # despam: func [e] [replace replace/all e ":" "."
