Greetings, I am yet another lucky person graced with an RIS this holiday season. I already seem doomed to buying more Lego sets for extra parts. I was quickly thwarted trying to build examples in Jonathan Knudsen's book which I assume is based on (...) (26 years ago, 14-Jan-00, to lugnet.robotics.rcx)

Hi All, As seen on the 2000 DK catalog, page 58 : (URL) Mars will be available in March... But there is a new set : the "Ultimate Accessory set". Any ideas what it contains ? Seems some light bricks and some sensors, remote control, tachometer ??? (...) (26 years ago, 13-Jan-00, to lugnet.robotics.rcx)

(...) If I were writing NQC from scratch, I'd agree. However, several years ago I was writing a preprocessor and bison wasn't available to me, so I hand-coded the parser. When NQC was started, I just reused about 90% of this parser. Of coruse, along (...) (26 years ago, 13-Jan-00, to lugnet.robotics.rcx)

Prof. Goos rather convincingly advocates generation as the do-all and (...) (26 years ago, 12-Jan-00, to lugnet.robotics.rcx)

Thank you, David. Your gode is great! I learned a lot from your quick example, though I prefer Java more. I will encapsulate RCX commands in some utility objects and use them in more higher level objects. What I focus now is make a RF/IR adapter to (...) (26 years ago, 12-Jan-00, to lugnet.robotics.rcx)

(...) OO works very well for things like a parse tree. I can add a new statement and just add its rules for semantic checking and code generation...all within its own class. I think part of the problem is that compiler design is a very heavily (...) (26 years ago, 12-Jan-00, to lugnet.robotics.rcx)

I should probably mention again that legOS supports C++, and supports it even better if you add void*builtin_new(size_t n){return malloc(n)}; to the appropriate library, as v0.3.0 will. The rest of this is off-topic. Dave Baum schrieb: (...) (...) (26 years ago, 12-Jan-00, to lugnet.robotics.rcx)

Hi Eric, Yes, I believe you could create a sensor object on the VB side and write your code thinking in terms of a sensor object. Here's one way: =-=-=-= BEGIN SAMPLE CODE =-=-=-= Private m_SensorNumber As Integer Private m_SensorType As Integer (...) (26 years ago, 11-Jan-00, to lugnet.robotics.rcx)

(...) but (...) More than that. You can (for instance) have a 'command' thread, which looks at a variable, and decides according to the values on this whether to turn left/right or issue some other response, and does this by changeing other values.
