| | | I have discovered a somewhat non-intuitive feature of NQC (in my version, at least, which is pre-2.0) The statement: var = (20 * var) / 21; gets compiled into the following: MUL var, 20 ; var = var * 20 DIV var, 21 ; var = var / 21 rather than the (...)

| | | | The optimization was intentional (and quite a lot of work, actually). I know it breaks with multiple tasks, but I was more concerned with keeping the variable pool from being cluttered with temporaries. With only 32 vars to use, its quite easy to (...)

| | | | Thanks, Dave! It will be good to have that in the manual, because it is a very confusing behavior that is difficult to track down. Variables take on values that are completely different from the values that the programmer is setting them to. Most (...) (25 years ago, 1-Nov-99, to lugnet.robotics.rcx.nqc)
