I just have to ask... compliance with what, exactly, and why? It's compiling code for a very unique hardware environment, so one would think that the addition of functions in support of that environment would be a good thing. Remember that the mere fact that there exists a predefined function for (for example) setup_adc() doesn't mean one is required to use it. I could, if I wanted absolute portability, write defines and whatever else for Compiler X in such a way that Compiler Y would compile the same code. Too inconvenient, you say? Hmm... I felt the same way about writing all those functions for Compiler Y before being able to do anything useful with it. Six of one, half dozen of the other. As for porting old projects to a new compiler... I have tried that on several occasions, not limited to PIC or C projects. I see it every day at work, where extensive development is done with C, C++, Java, VB, Oracle and other languages/platforms. I see code that isn't portable from one *version* of the same vendor's compiler to the next (Sun V4 to V5 or V6, for example), let alone from one vendor to another (like Sun's C compiler to GCC). Yes, in theory one could write strictly to some spec like ANSI C. In theory, there is no difference between theory and practice; in practice, there is a big difference. In the end, when I finish a project I have taken to archiving the project code along with the compiler that was used to make it work. It's the only really safe way to maintain the code later if you need to. Anyway... having said that, I have still not noticed a terrible lack of ANSI compliance with CCS, at least not that can't be eliminated with some typedefs and such. I'm not an expert on such matters, but you won't find a PIC C compiler that *is* completely ANSI compliant, I don't think a single one of them allows recursion for a start. And I'm not trying to make an argument for one compiler over another (though I make no secret of my favorite, and my reasons). I just hate to see decisions made based upon flawed logic, or those made that ignore the difference between theory and practice. Dale (My neighbor drives a far more expensive car than mine.
