I don't think there's any particular reason to believe that the generated code will be any faster?

I don't either. I think it's more of a syntactic trick than anything else. Gives us something to talk about on a Thursday afternoon, though, eh?

Problem with the toascii() w/ clarification            01/01/70 00:00      
   toascii not what you want            01/01/70 00:00      
      Ah yes.....makes sense            01/01/70 00:00      
         C does know ASCII            01/01/70 00:00      
            the final result:            01/01/70 00:00      
               That is a LOT of code            01/01/70 00:00      
                  It won't compile in its state because...            01/01/70 00:00      
               Grossly inefficient!            01/01/70 00:00      
                  A small trick            01/01/70 00:00      
                     small trick is cool.....            01/01/70 00:00      
                        Same as Neil's            01/01/70 00:00      
                           Ah makes sense.....            01/01/70 00:00      
                              You can still do better            01/01/70 00:00      
                                 LOL....Russ.......LOL            01/01/70 00:00      
                                    sprintf()            01/01/70 00:00      
                                       I had you at <>            01/01/70 00:00      
                                          So why not sprintf()?            01/01/70 00:00      
                                             You are right......I did say that            01/01/70 00:00      
                        How the small trick works            01/01/70 00:00      
                           Is it worth it?            01/01/70 00:00      
                              Same assembly generated for me            01/01/70 00:00      
                           You said index.....click click....very nice            01/01/70 00:00      
                              fast (sic?) lookup table            01/01/70 00:00      
                                 Faster? Probably not.            01/01/70 00:00      
               What's in a name?            01/01/70 00:00      
                  true.....but at this point.......            01/01/70 00:00      
                     Tricks and treats            01/01/70 00:00      
                     there is no time lost by doing it right            01/01/70 00:00      
                        You guys are completely right,            01/01/70 00:00      
                           the very simple way to (almost) do it right            01/01/70 00:00      
                           For the sake of learning            01/01/70 00:00      
                              Good point            01/01/70 00:00      
   UART doesn't know ASCII            01/01/70 00:00      
      Good point....but            01/01/70 00:00      
   Unhelpful documentation            01/01/70 00:00
