Hi Ammon: I'm not sure if I understand your question completely but: Here's what I do. 1)A (slightly) customized error maker 2)An error handling routine 3)A try-catch style template Error maker ========== ;############################################################################################## ; toss: Simple error-reporting function.

I have several error handling fucntions, but what I want is to actually redefine the system error handler of REBOL. For example: error-catch: function [] [] [;code that catches error] ;all the error producing code you want ;none of it is printed to console even though ;error-catch hasn't been called at all! (except ; by REBOL) basically I want to decide what REBOL does with an error reguardless of where it came from, or who produced it. Thanks!! Ammon PS I guess I will keep browsing the system object till I find it. I know it is their, Carl wouldn't have left it out. Enjoy!!

rutine, what is? One of you guys (or gals) surely knows what it is. I guess really what I am looking for is the word to set, after all, there are NO RESERVED WORDS, right?
