(...) Great. Thanks. This is a real lifesaver since I am deleting and reloading firmware at a rapid rate and my RCX is inside a construction which makes it awkward to get at the batteries. Now the delete/reload can be done entirely at the GUI. (24 years ago, 24-May-00, to lugnet.robotics.rcx.pbforth)

(...) Yes. Therefore you might want to use the truncation selection, which allows you to have only 1 copy of the population at a time to save memory. It worked for us, we have a small GA running inside of the RCX. We evolved a program with simple (...) (24 years ago, 24-May-00, to lugnet.robotics.rcx.legos)

I'm trying to define a constant in a compiled word. : zzz 1 CONSTANT ONE ; I know its not right. It tries to compile "ONE" which is not what is wanted. What is the right way to say this? (24 years ago, 24-May-00, to lugnet.robotics.rcx.pbforth)

Open the port on the host system using whatever language you want and proceed to send commands to it. Of (...) (24 years ago, 23-May-00, to lugnet.robotics.rcx.pbforth)
