[REBOL] Re: x: :y question

From: rebolek:seznam:cz at: 4-Feb-2003 9:38

Thanks Joel and Ladislav. I had an idea: I need to sroll some face up or down, left or right depending on some value. I can use something like: either x < 0 [a: a + 1][a: a - 1] so I thought I can make it more REBOLish ;), something like: op: either x < 0 [:+][:-] a: a op 1 This does not work, OK. But I cannot use even 'alias, becease aliased word cannot be changed :( and that's sad :(( alias: either x < 0 ['+]['-] "op" a: a op 1 This works only once, then I've got this error: ** Script Error: Alias word is already in use: op ** Near: alias either x < 1 ok, I'll use my old code. But Joel, what does mean your:
>> (+ 1 2)
== 3 ? I can't reproduce it, for me, it's always
>> (+ 1 2) >>
(nothing happens, because type? (+ 1 2) is op!) bolek
