[REBOL] Re: Using a Math oper. buried in a variable

From: anton:wilddsl:au at: 7-Apr-2009 3:46

Hi Scott, These apparent inconsistencies are not as inconsistent as they might seem. First, with "^^", you found the escape character. In any symbol set you will find "inconsistencies" around the escape character. What the above string represents is a single character ^. It just appears in code that there are two. The string you need to type can be found by doing this: to-string first [^^] but actually, now we remember that ^^ isn't the Rebol power operator anyway! It's **. Oh well. :-) Second, you can't inject parenthesis as if they're words, because they're not words. They are Rebol syntax at a more fundamental level than words. (I think that's a correct way to explain it, anyway.) If you want to create parens, then do it like this: append copy () something or to-paren reduce [some stuff] It's just the same with blocks and strings. They are all series! delimiters. " [ ] ( ) You can make the delimiters into words, but then how are you going to use them? Regards, Anton. Wall, Scott wrote:
