I see that I wa using the "to-integer' function in the wrong place... Your "op:" assignment line is of course the key (kudos to you) and I suspect contains a lot of "keys" to understanding REBOL. Nice little script! Thanks for the extra mile.... BTW, it works exactly as to what I had in mind. I don't _need_ this calculator for anything -- it's merely a learning project.
