It looks like Scout programs no longer need `#include "scout.nqh"', and the file has been removed from the NQC beta distribution. Is that correct? I've been confusing someone new to NQC because I didn't realize this :( --Ben (25 years ago, 11-Feb-00, to lugnet.robotics.rcx.nqc)

| | Re: Having trouble with -D option

You found a bug - NQC is actually defining D to be the tokens =1, which then leads to a lot of confusion later on. Basically I bungled the pointer math. I fixed the source so the next release (2.1 final) should be fine. I'll probably release 2.1 in (...) (25 years ago, 11-Feb-00, to lugnet.robotics.rcx.nqc)

(...) Same with 2.1b3. FWIW, #ifdef D task main() {} #endif works as expected. D is getting defined, just not to 1. (Or to any number.) (25 years ago, 11-Feb-00, to lugnet.robotics.rcx.nqc)

Here's the latest update. Hope we will get a clear picture of this #@$@ memory after all. The point is that the RCX processor can address 64k of memory, so let's divide this range into 4 equal area of 16k. (note:16k or 16384, in hex is 0x4000). (...)

Thank for the answer, Dave, this is the kind of info I'm looking for. BUT!
