Thanks, Tim. I haven't used the #x idiom myself - I like it. Your implementation with the boolean: (...) Will need an extra level of parenthesis surrounding the bool so that its declaration scope is made local. You can certainly go to town with this (...)

(...) For more fun with asserts: See if your compiler supports the FILE and LINE macros (or something equivilant). #ifdef NDEBUG #define assert(x) ((void)0) #else #define assert(x) if (x) else assertfail(FILE,LINE); #endif your assert_fail function (...)

(...) I agree it seems to be the wrong way round. That's the standard implementation. NDEBUG seems to stand for "No debug". One advantage of making it negative, is that you get the assert()s if you don't do anything (ie dont define NDEBUG). BTW, (...) (21 years ago, 8-Jan-04, to lugnet.robotics.rcx, FTX)

Hi, I recently bought the RCX2.0 and I am a little disappointed at the range for the USB tower. Though configured to be at long range I doubt I can implement a range greater then 5 or 6 feet. Is this normal.? Am I missing something.? Paul Reedman (21 years ago, 7-Jan-04, to lugnet.robotics.rcx)
