I think that would be incredible. Ever since I started working in REBOL, accessing and manipulating values within a series have always been problems for me. I'm so used to the array[index] format. Hah, course, there's another language, a game language, I've toyed with which allows access such as: array[1..$] array[3..$-5] etc, where '$' represents the end of the array, and '..' is, in case you haven't guessed, "all values between the specified values, inclusive". So [1..$] with an array that contains 10 values would be all values from array[1] to array[10]. This is most useful for working backwards or selecting portions of an array (data = source[4..$]; tag = source[$-3..$]; and so forth). That spoiled me quickly. Anyways, that's interesting news. And I hadn't thought of using 'min min'.. saves me the hassle of reduce and pick.. Like I said, I'm rusty. Thanks all. --Charles
