[Slightly OT]..the Keil blinky example uses software timing loops...[SOT]

Without using or even mentioning 'volatile'.

What a poor example - they should know better!

(I wonder if Jon Ward of Keil still reads this...)

            So don't keep blaming the tools, then!            01/01/70 00:00      
               I've repeatedly said ...            01/01/70 00:00      
                  where is the qualifier?            01/01/70 00:00      
                     ISTM that some things simply won't work in 'C'            01/01/70 00:00      
                        Of course that is true            01/01/70 00:00      
                        exactly!!!            01/01/70 00:00

                           It's not entirely separate ... but it is an eval-issue            01/01/70 00:00      
                     That's a KEIL-specific limitation. it IS a KEIL problem            01/01/70 00:00      
                        It is a universal problem for all software makers            01/01/70 00:00

                  Going with that            01/01/70 00:00      
                     It's a tradeoff ... Isn't it?            01/01/70 00:00      
                        More generalisations            01/01/70 00:00      
         It's already been "rolled"            01/01/70 00:00

      An excellent article            01/01/70 00:00      
   It is Programmers Decision            01/01/70 00:00      
      Not so trivial to decide            01/01/70 00:00      
         The problem isn't with 'C' vs ASM ...            01/01/70 00:00      
            How many 'C'-coders would be willing?            01/01/70 00:00      
               Not the worst examples, but the preponderance, Andy            01/01/70 00:00      
            Much use of fixed-point in C code            01/01/70 00:00      
               It's not what they're taught to consider            01/01/70 00:00      
                  I don't know about everyone else            01/01/70 00:00      
                     Now wait a minute ...            01/01/70 00:00      
                        Lots of people can't program...            01/01/70 00:00      
                           What are you advocating, Per?            01/01/70 00:00      
                              Oh, Come On Now...            01/01/70 00:00      
                                 I have to admit ...            01/01/70 00:00      
                                    TTM and product lifetime            01/01/70 00:00      
                                       That's very true ... sadly ... but ...            01/01/70 00:00      
                                 if you really did do this you would come away a convert            01/01/70 00:00

                              C++            01/01/70 00:00      
                              oh, how 'crappy' they would be            01/01/70 00:00      
                                 Don't be so sure ...            01/01/70 00:00      
                                    irrelevant to C or asm,            01/01/70 00:00      
                                       Nobody has questioned your competence            01/01/70 00:00      
                                          you missed the point            01/01/70 00:00      
                                             Don't you think design style has something to with that?            01/01/70 00:00      
                                                you must be off your rocker            01/01/70 00:00      
                                          Don't confuse the tool with the user            01/01/70 00:00

                     Maybe not so ridiculous ...            01/01/70 00:00      
                        A + B != C            01/01/70 00:00

                     I don't think so much PC either - just beginner accidents            01/01/70 00:00
